Page 3 - 10-5 scratch-dig Flat Windows

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.

Super polished technology is an optical fabrication technique developed specifically to achieve minimal roughness values. CASTECH manufacture the super polished substrate which is able to achieve below 2 Ǻ roughness levels on materials such as fused silica, and optical glasses . And the roughness are measured by Zygo NewView 8300 and AFM.

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 ...

Parallel Windows are similar to Plane Windows, but with parallel surfaces. These windows are well suited for applications in which angular deviation of the transmitted beam must be kept as small as possible. Misalignment errors are also minimized when the window is repeatedly inserted and removed. Round, square, and rectangular ...
