Optical Windows Laser Window Infrared Brewster - China

price: contact company for price

Optical Windows are flat, plane-parallel plates that are often used as

protective barriers for electronic sensors or detectors from outside

environments. Optical Windows should be selected based on the material

transmission or mechanical properties of the substrate. DeLn Optics’

Optical Windows are offered in a variety of substrates, such as Ge, Si,

N-BK7, UV Fused Silica, ZnSe, Multiple anti-reflection coating options

are available for the UV, visible, or IR.

Brewster Windows are uncoated substrates of laser grade surface quality and parallelism that are designed to be used at Brewster’s Angle (the angle at which p-polarized light incident on the surface is not reflected). At this angle, p polarization reflectance drops to zero. When used in a laser cavity, a Brewster Window reduces the cavity loss for p-polarized light compared to s-polarized light. The result of preferentially reducing the loss along one polarization axis is that the laser will emit linearly polarized light.
