Product Description


Germanium windows used as transparent barriers for sending and receiving light between two phases under varying conditions in temperature, pressure, chemical composition, cleanliness, and phase.

Germanium transmits in the IR range, from 1.8µm to 23µm,at which Germanium offers higher internal transmittance. Moreover, IR transmitting materials are generally much more expensive than their visible light counterparts so it is very important to select the right material for each specific application.

Non-coated and AR coated products are available.
