Co Spinel - Laser Crylink

Windows is an optical flat plate that does not change the optical magnification and only affects the optical path in the optical path.

It can be used to guide light into optical systems and isolate dust and water vapor, thereby protecting the internal components of the instrument. As a protective and sealing window for instruments or components, the light window is required to not affect the image quality and accuracy of the system.

Therefore, sometimes it is necessary to have high requirements for transmitted wavefront distortion, high transmittance, and high parallelism.
