windows

Jiheng Optics polished all the windows to a laser grade finish on both sides. They are intended for transmissive use and parallel better than 3 arcmin or 10 arcsec. Contact Jiheng Optics with your requirements for application.

We can supply as below:

--Circular windows

--Squareness windows

--Wedged windows

--Elliptical windows




Jiheng Optics will manufacture strictly under MIL-13830B quality standard. We support COD to insure your benefit.

Brewster Windows
circular windows
Jiheng Optics can provide you with the laser grade windows. The windows are designed for a wide varity of laser window and beamsplitting applications. In addition to use a laser windows, they may also be used a substrates for near infra-red coatings to form output coupler, beam combiners, or plate polarizers. Laser Windows may be anti-reflection coated to reduce the losses due to reflection from the surface. Mirror mounts are available.

elliptical windows
Jiheng Optics can provide you with the laser grade windows. The windows are designed for a wide varity of laser window and beamsplitting applications. In addition to usde a laser windows, they may also be used a substrates for near infra-red coatings to form output coupler, beam combiners, or plate polarizers. Laser Windows may be anti-reflection coated to reduce the losses due to reflection from the surface. Mirror mounts are available.
