Optical IR Germanium Windowa Ar Coating @8- 14um

Product Description

Product Description
Optical windows are falt, plane parallel plates which are often used as protective barriers for electronic sensors or detectors from outside environments. When selecting windows, please consider materials, transmission, scattering, parallelism and resisitance to certain environment or mechanical properties of the substrate.
