TEN.Optics (OptiSpark, LLC, a part of the TechnoSpark Group of Companies) manufactured a complex stack light filter within the OIC 2019 Manufacturing Problem Contest and turned out to be the only Russian company that passed qualification for the event. The results were summed up in June.
According to the contest terms, the participants were supposed to create a light filter that was to smoothly pass and then smoothly increase the intensity of the polarized light spectrum at the angles of 10 and 50 degrees; the design of this coating had to be calculated independently. Two independent laboratories were appointed to assess the submitted samples as to their transmittance spectra, coating layers and merit functions. The contest qualification was passed by the companies from the United States, Japan, Germany, France and Russia. TEN.Optics, a contract manufacturer of complex optical coatings, was the only Russian company to take part in the contest.
The TEN.Optics team presented the most economical filter as to the number of layers and thickness. “The process we used to produce this light filter is two times cheaper and ensures quality comparable to that of the other competitors. While completing a commercial order for this type of coating, we would spend considerably less machining time and materials than the other participants,” Vladimir Ponomarev, the company director, said.
As for the merit function parameter, the coating design presented by TEN.Optics took the second position.
This competitive sample was made by the company using Buhler SYRUSpro 710 electron beam evaporation unit. “Our rivals used the equipment that can give at least 10 times more accurate results, but costs twice as much. As a Buhler partner, we’re glad to show once again the tremendous potential of this equipment,” Vladimir Ponomarev added.
TEN.Optics manufactures customized multilayer optical coatings of higher complexity that are used in communication and navigation equipment units, excimer laser systems and other facilities. The company specializes in high-precision light filters with high transmittance and blocking levels.
