Windows
Optical Windows are flat, plane-parallel sheets, often used as protective barriers to shield electronic sensors or detectors from external environmental impacts. When selecting Optical Windows, they should be screened according to the material transmission properties or mechanical properties of the substrate. Optical Windows will not change the magnification of a system.
