Thomas Waineo, 1935 - 1996

EARLY DAYS
As if his vision problems were not enough, he developed a severe ear infection at age seven. The internal scarring left him nearly totally deaf. He could only hear a very narrow range of mid-frequency sounds with a hearing aid. Despite these handicaps he developed an interest in astronomy and became a very active member of the Detroit Astronomical Society. He quickly mastered the craft of telescope making and became an instructor. As he strove to construct more difficult instruments, he also gave freely of his time to teach others the art of mirror making.
He did not admit that he had spent all his travel money on his hotel room at North Station and had not eaten in two days. His wife related this misfortune just recently. Soon we were making seventy five cents an hour as optical technicians.
Recently, a thirty year classification was removed from the program we worked on, code name "CORONA". We learned that the opticians played a key role in advancing the art of reconnaissance technology and made the lenses for the first surveillance satellites. Our "customer" was the Central Intelligence Agency. Our efforts were under scrutiny from politicians and Air Force colonels, alike. We worked under tremendous pressure to meet the launch schedules. One visitor was Robert O. Woodbury, author of "The Glass Giant of Palomar".
Tom had a unique method of removing all distractions from his polishing effort....he shut off his hearing aid!
In the beginning, many of our lenses were blown to smithereens, as one booster after another exploded on the launch pad or during ascent. Successes finally occurred and the project eventually resulted in the downfall of the Iron Curtain in 1989.
Our vacation was a trip to Stellafane, Vermont, the mecca of Telescope Nuts (TN's) around the world. 1960 was the year that a hurrricane tore up the Connecticut Valley and drenched the convention. An Itek friend had given us a ride and we all had to chip in to pay the farmer to haul the car out of the mud.
I drove to his apartment in Boston's Back Bay and then headed westward, well before dawn. We crossed southern Ontario, through Windsor, and then into Detroit late the next afternoon. Tom did not have a license because of his vision, so I drove the eight hundred miles straight through from Boston.
In Detroit, Tom introduced me to his Mom and Dad who were concerned over the distance we drove. Then I met many of his five brothers and four sisters. They are of Finnish descent and all have light blonde hair and looked much alike. I had trouble differentiating them. Tom was second youngest. Exhaustion quickly set in from the long trip and sleep came quickly.
Twelve hours later, I thought I was dreaming that my big toe was being crushed by a lobster (I was a scuba diver). I startled awake. Tom's father was standing by the bed squeezing my foot. Time for breakfast. This had been his way of waking Tom up to go to school because Tom took off his hearing aid at night. We spent a number of days meeting with amateur astronomers, telescope makers, and visiting the city. There were times of relaxation and he told me of his passion for sailing on Lake St. Clair with his brothers and sisters. We toured the big auto plants. His father was a lifelong Ford employee and he kidded me about the cheapness of my compact little Chevy Corvair.
Tom brought me up to the family summer retreat on one of the many small lakes that dot the lower peninsula of Michigan. Here we enjoyed swimming and picnicking with some of his family and had a day of relaxation. We then headed northward to the upper peninsula, seeing the sand dunes along the east coast of Lake Michigan, and the locks at Sioux Ste. Marie. The region reminded me much of the desolation and wilderness of Maine logging country.
We camped on the shores of Lake Superior. I will never forget trying to swim in the icy water. Being of Finnish descent, it did not bother Tom at all, but it reminded me of winter ice diving in New Hampshire. We toured the Nickel mining towns near the Canadian border and then travelled southward through Wisconsin dairyland. We arrived the day before the Astronomical League convention began.
The highlight of the trip was a field trip to Williams Bay, Wisconsin and a tour of the Yerkes Observatory. We were lucky that it was completely clear that evening and we were able to view M13, the Hercules star cluster, with the world's largest refractor, the forty-inch diameter Alvin Clark instrument. I am not sure what Tom saw, but I know he had good central acuity. My eye was locked to a long viewport into space. At the other end, was the spectacle of one hundred thousand dazzling stars set like diamonds on a velvet sky. A slight shimmering from air turbulence added a dynamic effect and seemed to add depth to the illusion. For me, the effect was as stunning as seeing the crown jewels at the Tower of London. I had to be pulled away from the eyepiece so that someone else could look.
After that trip, Tom set off on a quest to build telescopes that might duplicate our experience at Yerkes. He also realized that amateur conferences were a great way to present and talk up new optical designs and to share ideas. We returned to Boston, brimming with new plans for new projects. Itek moved to an enormous new facility in Lexington and we continued producing lenses to the highest quality we could achieve. Fortunately, we did not know which space birds were ours. When a satellite failed to orbit or burned up on reentry, we shrugged, assumed it was a biology experiment and continued working.
In hindsight, we probably would have been demoralized by the number of failures. The next summer, Tom suggested we get away from the 'daily grind' by taking a windjammer cruise through the Bahamas for our vacation. The trip gave us an opportunity see some southern constellations and hooked us onto the tropical charisma of Florida. I left Itek in late 1962 to join a spinoff company, but Tom stayed on to work on a development project to make accurate and stable aluminum mirrors.
For the new research effort, Tom was asked to make each
mirror to a surface accuracy of one millionth of an inch ( Lambda over
twenty). The mirrors were then heated or submerged in super-cold liquid
Nitrogen. Most often, the mirror would warp into a twisted wreck with an
error of many light waves. The test engineers would then note the results,
execute a new thermal cycle process, and then meekly return the mirror
to Tom for refiguring.
As we commuted to work, Tom and I learned much about life
and love from these old-timers, and even some secrets of the trade. In
the evening, we chatted in the coffee houses of Kenmore Square or had a
few beers together. As our careers progressed, we saw a transition in this
field of endeavor from art to technology. The optical craft still places
great demands on the tyro.
We all felt relief at working on a new astronomy program, but the stresses of working to micro- inch tolerances on much larger optics was also a strain. The pressure of meeting a launch schedule also remained. Tom fabricated two very difficult 25-inch oblate spheroids for the OAO that undoubtedly prepared him for the challenge of fabricating telescopes of the Wright-Schmidt configuration.
Three years later, we were stunned when the booster rocket for the OAO ran out of fuel and the telescope payload crashed into the Indian Ocean. We had built a single backup but NASA could not get the funds from Congress to launch it. The experiments were never repeated until the launch of the Hubble telescope, twenty four years later. The telescope was finally transferred to Langley and reconfigured as a Laser Transceiver and flown on a Shutle mission.
Tom left D.L. to join Space Optics Research Laboratory
(SORL) which was founded by Robert Galipeau in Sudbury, MA.. Mr. Galipeau
was a graduate of the University of Rochester and was interested in fabricating
aspheric surfaces for a variety of applications, both space and terrestrial
optics. Tom met the challenge of this small company by devising many unique
methods of making conic surfaces.
The only drawback to his design was that he placed the location of the prime focal plane internally; between the Newtonian diagonal and the side wall of the telescope tube. This minimized the obstruction. He used a commercial camera lens (a Macro-lens) to relay the focal plane to an accessible position. This lens introduced some noticeable aberrations, but the wide field was impressive. This compromise could be overcome now-a-days by mounting a miniature CCD camera to the back of the corrector lens . Of course it would no longer be a visual instrument.
Tom was adept at putting collimators and test setups together
with structural steel, red wax, and masking tape. He completed many projects
under budget with this spartan approach and the company profited and moved
to larger quarters in Chelmsford. Eventually, it became a division of the
Intergraph companies. He met his singular love, Marie, in Chelmsford and
he became a married (and happier) man. In 1972, the Viet Nam War ended
and Diffraction Limited was downsized into oblivion and the workers (including
the writer) laid off; while Tom continued polishing at SORL.
The advantage of metal optics are superior durability in a hostile environment where survival is more important than ultimate figure accuracy or figure stability. New fire control systems were developed for application on a new generation of tanks. Metal mirrors would not shatter like glass, if hit by shrapnel.
In this same 70's era, the Mariner Jupiter- Saturn (MJS) project was in development at the Jet Propulsion Lab. The mission was to be a "Grand Tour" of the planets for the 1979 alignment. Texas Instruments Corp. and JPL selected AOC to produce six infrared telescope systems of Cassegrainian design but with a very short f/0.8 primary. The experiment was to search out warm patches on the outer planets, do temperature measurements, and perform Infrared Fourier Spectroscopy of gaseous elements and compounds. The project evolved into the Voyager Mission. It was determined that Pluto was not practical to reach, but both flight spacecraft would go to Uranus and one would continue to Neptune.
Applied Optics had a "do-or-die" mission. If three instrument sets could be machined, polished and coated, assembled, and tested in a cryogenic space chamber - all produced in a two year time period, then the instrument would fly under the direction of principal investigator (PI), Dr. Rudolph Hanel of Goddard Space Flight Center. If the instrument failed, then JPL had prepared an aluminum panel to cover up the telescope attachment platform. If we could produce another three to a more rigorous and much colder thermal requirement, then two of those would fly.
In addition to my duties as test engineer, I had rolled up my sleeves and helped polish the mirrors. The primary mirror was made of beryllium and weighed only four pounds. Figuring it was a bear and we were falling behind schedule. Remember, the alignment of the planets was not going to wait for us to finish. While I began work on assembling and testing the first telescope, Tom joined us at AOC because aspherics were no longer a high priority business segment at SORL. He was assigned to make the flimsy primaries and I later tackled the hperboloidal secondaries. Soon I found him pulling his old trick,shutting off the hearing aid! Before long, we were back on track.
It was on this project that he showed my another of his figuring tricks. He poured a very thin layer of pitch onto a balsa wood strip and then polished the high zones with it. He oriented the flexible grain direction so that it could better follow the aspheric departure in the radial direction of the zone. The more rigid axis was placed on the chordal axis of the zone where it could stay in contact with the surface. In this way, severe aspherical surfaces could be smoothed and blended, while a dwell on the high zones would remove them.
Unfortunately, one of the last primaries made showed an unusual figure defect at cryogenic temperature. NASA made the conservative decision to fly the earlier optics which would have reduced thermal sensitivity.
In 1987, the Voyagers II and I passed the orbit of Neptune, after a thirteen year journey of spectacular discoveries and observations. Both spacecraft are now in interstellar space and the sun shines on them only as a bright star. The optics are now almost as cold as absolute zero but the mirrors did not crack. Both spacecraft are now on a lonely journey to the depths of eternity. Tom's workmanship goes with them.
The AOC telescopes made many measurements and even succeeded in detecting the warm spots associated with the volcanic activity on the Galilean moon, IO.
NASA also developed an interest in earth observations
and funded a series of weather satellites to be operated from geosynchronous
orbit. The Santa Barbara Research Center of Hughes Aircraft designed a
set of highly corrected Ritchey-Chretien telescopes to scan terrestrial
weather patterns over a wide range of spectral bands. AOC was the successful
bidder to produce the beryllium mirrors for that application. The time
lapse videos that were seen nightly on TV, during the weather broadcast,
recorded storms, clouds, temperature readings, and the spectral signature
of the ground below. Tom played a key role in the figuring of many of these
18- inch aperture telescopes.
Tom had an extended family that included two step children. His favorite pets were his bull mastiffs, Yanu and Timmy. Tom and I corresponded occasionally through the years. He came up to the Stellafane telescope makers convention to demonstrate the Maksutov family of tests.
Three years ago (1993), I visited Tom and Marie in Bradenton. My kids were performing at WDW with our high school band and we skipped over to the Sarasota area in a rental car. Tom was attempting to ray trace optical systems with an original 8088 IBM PC with monochrome monitor. He would flip up his glasses and study the screen word by word, number by number from a distance of a few inches. Yet, he was learning more about lens design.
He was later "put out to pasture", as he said it, from
AOC. The company was no longer getting enough business and there was too
much competition. The owners closed the doors, just as had happened to
me at D.L., and just recently (1996), to Itek. A very few Itek people struggled
on for a few years under various managements. Eventually we will be replaced
by robotic machines.
He had to ask for telescope mirror projects from amateurs, to keep busy. His friends in Bradenton put a 386 PC together for him and he was off on Compuserve and the Internet, spreading his love of the stars and ways to see them better. He also described a simple-to-build polishing machine for amateurs.
It was very difficult to talk to Tom and for him to understand me via long distance telephone. The PC and e-mail solved this problem. To the week of his death, he was communicating with amateur astronomers around the world. He was sharing his great knowledge of Optics and the technology of his craft.
I visited him and Marie again in April of this year (1996).
He had put on weight and I felt this was a bad omen. He had had by-pass
surgery some years prior for a weak heart function. He told me he was completing
a 17-inch Ritchey-Chretien for an amateur in Maryland, by using a finite
source and despaced mirrors. The idea came from Mel Bartels and was developed
over the Internet. This unique approach makes it very simple for an amateur
with limited equipment to make a set of optics that is otherwise very difficult
to fabricate.
Mr. Levin shipped the primary miror to me at work, to see if Tom had completed it. I regretted to report that the smoothing of the hyperboloid was not finished and was severely overcorrected. I have conferred with some other experts and we felt it would be best to redo the last grinding step.
Tom's new-found hobby of electronic communication gave
his life a new meaning to his very last day, according to Marie. I will
never forget his dogged determination and stubbornness to extract the highest
level of accuracy from every piece of glass he rubbed on....and that included
the polishing of a 24-inch diameter full thickness mirror, well over 100
pounds, on top of the lap because a machine was not available.
What determination!
In November, 1996, Tom's ashes were spread on Sarasota Bay, on the ocean he loved so much. That evening, many of us around the world, looked to the stars in the ocean of space in rememberance......and the Voyagers sail on!
Any comments or questions are appreciated.
