Optical Windows are flat, plane-parallel plates that are often used as protective barriers for electronic sensors or detectors from outside environments. Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system.
General Purpose plane windows-Flat polished surface, Laser finish both sides, Apply any anti-reflecting coating. These general purpose plane windows are polished to λ/10 flatness except where indicated otherwise. They are intended for transmissive use and are parallel to better than 3 arcmin or 10 arcsec. Select a coating appropriate to your application or contact us with your special coating requirements.

Optical Design
There are eight professors in our scientific research team. All of them come from Chinese Academy of Sciences, Changchun Institute of Precision Machinery and Physics. We can supply design Optical System according to your demand.
Processing & Testing
We have more than50 advanced milling grinding, polishing, plating equipments from The Unite States and Japan. And also introduced the ZYGO horizontal laser interferometer, AK100 horizontal laser interferometer, LAMBDA950 spectrophotometer, the focal length meter and other test equipments.
Optical Coating
We are coat from 0.2um to 20um. Including AR coating, high reflect film, the splitting film, laser crystal film, IR film, UV film and Optical fiber film etc. Especially in the laser, the frequency doubling crystal, IR crystal, and UV band coating we have huge advantage.
