Did you know that ISP Optics has been diamond turning lenses and mirrors since 2001? Over the last decade and a half we have fabricated many thousands of sphere’s, asphere’s, diffractives and mirrors for our satisfied customers.

Over the past 12 months, due to high demand, we have made major expansions in our diamond turning department by nearly doubling our capacity with the addition of three new diamond turning machines. Our diamond turning department now consists of eight diamond turning machines from both Moore Nanotechnology and Precitech. This makes ISP Optics one of the most diverse and agile DT operations in the world and allows for us to provide fast, high quality solutions for our customers. ISP Optics also has state of the art metrology equipment from Zygo and Taylor Hobson all within our temperature controlled facility. Our skilled team of diamond turning engineers and technicians has over 100 years of combined experience which gives us the ability to meet the most challenging customer requirements and specifications.

When it comes to the diversity of infrared materials and the scale of production orders, from prototyping to high volume, ISP Optics has one of the most versatile operations in the photonics industry. Our unique diamond turning capability extends to nearly every material that transmits in the infrared, including standard IR materials like silicon, germanium and zinc selenide. ISP Optics also works with not so common materials like chalcogenide glasses such as IG6 or Amtir. Even various plastics like PMMA or Zeonex are diamond turned at ISP. KRS-5 and CdTe aspheres are manufactured using specially developed processes and techniques along with dedicated safety equipment. ISP Optics also works with non-ferrous metals such as nickel plated substrates, aluminum and copper parts to make high quality mirror surfaces. 

ISP Optics diamond turned components can be found in such applications as UAV gimbals, commercial and military thermal imaging devices, handheld FTIR cameras, IR telescopes and other cutting edge projects including an intraocular contact lens to help treat age related macular degeneration.

If you have any questions about our diamond turning capabilities or if you have any aspheric or diffractive surfaces you like us to diamond turn, please call as at 914-591-3070 or email us at


2015 ISP Optics lenses have once again made the news. ISP Optics, working with Joe Ford (University of Southern California) and Eric Tremblay (EPFL Switzerland), have produced an intraocular contact lens to improve the sight of people with age-related macular degeneration, the third leading cause of blindness globally. ISP Optics has been working with UCSD since 2008 on the continual development of these special lenses and looks forward to continuing this groundbreaking work with Joe and Eric.

2014 As a continuing effort to vertically integrate the manufacturing capabilities of ISP Optics Corporation, the brand new DLC (Diamond-like Carbon) coating system was installed in April 2014. The coating system is now fully operational for production.
New DLC Coating System (Plasma Enhanced Chemical Vapor Deposition) provides the ultimate hardness and durability to protect exterior surfaces of  Infrared optical elements in harsh environments. The advantages of DLC protective film are: wear and abrasion resistance, anti-reflection from SWIR to LWIR, resistivity to atmospheric corrosion and marine environment. These are crucial requirements to operate IR optics in the field.
ISP Optics offers DLC protective coatings on Germanium optics (for LWIR) and Silicon optics (for MWIR) as standard coatings. To find out more about ISP’s DLC protective coatings please click here.

2013 ISP Optics is celebrating 20 years of providing quality products and services to the photonics industry and we take this opportunity to thank our customers and our team. ISP Optics grew and prospered because our customers afforded us the opportunity and extended loyal support over the years and our team's contributions. Your products requirements, new technologies, new applications and our "listening" to you steered us in the forward direction. On April 5th we honored our long-time employees and celebrated their contribution to our growth and success.

ISP Optics Corp. of Irvington,NY felt the recent recession "almost immediately" in late 2001, company President Joseph Menaker said. And the response of the company, which makes optical devices for scientific products, was to invest more money in its factories and equipment.
That strategy appeared to fly in the face of common sense, but while the company went through difficult times, Menaker said, it had to think ahead. "We knew it (the recession) would be over sooner or later. In order to grow, you need a lot of investments up front to ramp up production, to buy more raw materials, and to train people."
Last year the company started hiring more of its highly skilled workers, "who need six to 12 months of training just to get to some basic level," he said.
That investment has been paying off for about a year now. In the first nine months of this year, the company grew 38 percent, compared with the same period a year before. In all of 2003, he said, ISP Optics grew only 8 percent.
ISP's current growth comes at a time when the photonics industry - businesses that make scientific instruments involving the use of light - is growing at roughly 5 percent to 15 percent, said Wendy Laurin, group publisher of Photonics Spectra magazine. ISP's segment of the industry - infrared optics - is growing somewhat faster, but not as high as 38 percent, she said.
Infrared optical equipment - often consisting of high-quality lenses, prisms and fibers - is used in a wide variety of instruments, including NASA telescopes, medical equipment and night-vision devices used by the military.
ISP has a history of investing in technology and a history of high growth. This year, for the fourth time in a row, it was named a "New York Technology Fast 50" company by Deloitte & Touche L.L.P. The award is for fast growth of a technology company over a five-year period. ISP ranked No. 43 on the list, with total growth of 44 percent over the five years from 1999 through 2003.
One factor in ISP's success has been a combination of attention to high quality as well as fast delivery, Menaker said. To accomplish both, the company has emphasized staff training in modern management techniques.
"It requires a lot of discipline, a lot of training and a lot of effort just to train our people," Menaker said. Even though labor costs are relatively low in former communist countries, he said, ISP Optical doesn't compete so much by undercutting prices as by investing more in quality and good service.
Richard Santos, senior purchasing agent for Zygo Corp. of Middlefield , Conn. , is one of the impressed customers. "They were very responsive in terms of meeting my time schedules," he said. "We've been very happy with them. The thing we look for is price and (quick) delivery, and quality - and their delivery for us has been 100 percent on time.
"Our plans are to move more toward assemblies and systems," he said, "to step up our production - not to be a component manufacturer, but maybe assembly for optical systems." Mark Lifshotz and Joseph Menaker , co-founders of the optical manufacturing company.
