In 2019 Precision Optical made strategic investments into thin film coating capital equipment. We acquired a new Perkin Elmer Lambda 1050 spectrophotometer equipped with the Total Absolute Measurement System (TAMS). TAMS gives us a combination of the highest degree of flexibility and accuracy with the 1050 for UV/ViS/NIR applications. In addition to measuring bi-directional transmittance a reflectance at variable AOI ranging from 5-80° we can also measure angular resolved scattering (BRDF/BTDF). Precision Optical also acquired a new Tecport thin film coating chamber which was installed in March 2019. This brand new Symphony 12 is a large format (1200mm) e-beam evaporator, with ion assisted deposition, enabling the manufacture of more complex thin film custom coating designs.

In 2017 and 2018, Precision Optical successfully manufactured multiple large optical flats. These reference optics had apertures > 600mm, and some weighed nearly 200 lbs.! With months of engineering, design reviews, and tooling and equipment development, Precision Optical was able to repeat the necessary optical performance to prove that we could deterministically achieve success.
Laser systems require optical components made with extremely high quality raw materials. These materials, combined with proper machining, controlled grinding for sub-surface damage removal, ultra-precision polishing and extremely robust thin film coatings are required to meet the demands of HEL (High Energy Laser) systems.
Precision Optical’s core products for nearly the past 60 years has been extremely precise prisms and prismatic optics. While we will continue to be an industry leader in the production of customized optical components, we are pleased to once again offer catalog right angle prisms and now offer catalog porro prisms!
In 2016, Precision Optical produced multiple optical flats greater than 600mm in diameter. Our nearly-60 years of engineering and manufacturing experience, coupled with our fabrication and state-of-the-art metrology equipment, has allowed us to successfully delivery optical flats of this size.
One of Precision Optical’s core products for the past 55 years has been the corner cube retroreflector. To this day, our ability to produce high quality corner cubes in volume is virtually unparalleled in the industry. While we will continue to be an industry leader in the production of customized optical components, we are pleased to once again offer catalog corner cubes!
A common element used in optical systems is known as a beam splitter. Beam splitting optical assemblies and elements play an integral role in optical systems by splitting, combining, and controlling the directions of multiple beam paths. Specialized thin film coatings applied to optical surfaces divide beams of light into separate wavelengths and polarization states with specific targeted values of transmittance and reflectance.
With a combination of a highly skilled work force, tons of capacity, high-end large aperture metrology, thin film coating and assembly capability, Precision Optical can be your “one-stop shop” for large optical flats and windows.
Precision Optical utilizes its arsenal of metrology equipment on all products delivered, where 100% inspection of finished articles is often required. In addition to using metrology equipment for fully furnished optical components, coatings and assemblies, we also offer metrology services on customer furnished materials.
Building upon decades of optical assembly experience, Precision Optical is pursuing an expansion of the assembly services we provide to our customers. Precision Optical possesses a diverse set of assembly capabilities that includes custom prisms, mirrors, windows and lenses, in sizes ranging from 3mm miniature optics to large 500mm optical flats.
Precision Optical has 55 years of precision manufacturing experience, and alongside our other high quality component products, such as corner cubes, penta prisms, optical flats, and custom prisms, we can produce some of the best alignment cubes in the market.
In recent years we have seen a growing demand for coat-only services, and Precision Optical is fully able to fulfill the diverse requirements. While significantly expanding the types of optical coatings we offer on substrates manufactured in-house, we also have grown in our ability to precisely schedule and maximize coating runs for efficiency gains.
Precision Optical manufactures thousands of porro prisms every year. Porro prisms can be made in all sorts of shapes and sizes. A common type that Precision Optical offers is a sharp roof or “knife” edge porro prism.
Precision Optical has added two new interferometers, a new 4D 6” AccuFiz Fizeau© for its Polishing Department, and a Zygo Verifire ATZ© with a DMI radius slide to its Quality Assurance Department.
Precision Optical has acquired its first 3D printer, and with it has added new rapid prototyping, tooling, manufacturing, and engineering capabilities.
Precision Optical has a long history of producing extremely precise optical flats. Even more so in recent years, Precision Optical has enhanced its ability to manufacture optical flats by adding more continuous polishers, higher-resolution metrology equipment, and large aperture interferometery.
Precision Optical recently acquired a NanoCam Sq dynamic surface profiler from 4D Technologies. This lightweight, portable profilometer has dynamic surface acquisition. This means rather than placing optics underneath the instrument, the instrument itself can be moved to, or on top of the optic under test.
Precision Optical recently acquired a custom-designed Goniomat M5 XL from Vermont Photonics. This compact, high precision goniometer, manufactured by Moller-Wedel Optical, is ideal for making in-process measurements within our polishing department.
Precision Optical has greatly enhanced its angular and beam deviation measurement capabilities through the acquisition of a PrismMaster HR Mot goniometer from Trioptics USA. The goniometer is an extremely valuable addition to our shop, providing us with the capability to obtain absolute angle measurement capabilities, as opposed to the relative angle measurements obtained using traditional autocollimation techniques.
Precision Optical has been selected to manufacture several of the optics for Keck Cosmic Web Imager for the W. M. Keck Observatory telescope atop Mauna Kea on the Big Island of Hawaii.
Precision Optical manufactures custom corner cube retroreflector with ¼ arc second average beam deviation, 1/20th arc second angles, and 1/8 wave transmitted wavefront.
Precision Optical has recently expanded its capabilities to include the assembly of large optical flats into metal housing assemblies. The large optical flats are manufactured in house to meet exacting surface quality, flatness, and homogeneity specifications before being assembled for our customer’s application requirements.
The NOVA-ASTRON Optical-Infrared Instrumentation group in The Netherlands is a national institute that develops instrumentation on world-class optical telescopes to serve the Dutch astronomical community. Currently MATISSE (Multi-AperTure Mid-Infrared SpectroScopic Experiment) is being built.
