Flat circular optical window

H-K9L

Optical Windows Φ10.0mm Thickness=2.0mm λ/10 Uncoated H-K9L optical glass Short Description: Optical Windows are flat plane-parallel plates, which are often used to protect electronic sensors or detectors without blocking optical transmission. Optical Windows are flat plane-parallel plates, which are often used to protect electronic sensors or detectors without blocking optical transmission. Optical Windows do not change the magnification of a system. Grand Unified Optics offers a variety of optical windows, which cover the wavelength range from ultraviolet (UV) to infrared (IR).
