Page 2 - lambda/8 Flat Windows

Rectangular Windows are offered in variety of materials such as BK7, B270, UV fused silica. which material is selected as windows is decided by material transmission and mechanical properities od materials.The windows are used to protected whole optical system, electronic detectors and sensors from some harsh outside environments.

Brewster Windows are uncoated substrates that can be used in series as polarizers, or to clean uo a partially polarized beam, When positioned at Brewster\'s angle, the P-polarized component of the light enters and exits the window without reflection losses, while the S-polarized component is partially reflected.

Optical Window: Optically flat, double sides parallel polishing of the optical glass into a relatively high precision of the surface. Mostly it is used for the testing or assembly equipments in order to allow light get into the testing machine or the instruments. PHYO Optics provide many different type of windows using various ...

Germanium is well suited for IR laser applications. Due to its broad transmission range and opacity in the visible portion of the spectrum. It also acts as a longpass filter for wavelengths greater than 2 µm. In addition, germanium is inert to air, water, alkalis, and many acids. Germanium\'s transmission properties are highly ...
