A viewport, sometimes referred to as a window, is an optical component that provides a means for visual, optical or broad-band energy transmission in and out of a vacuum system.

There are two types of viewports offered, zero-length and tubulated. A zero-length viewport has a thickness no larger than that of its mounting flange. This makes it easier to protect from accidental damage as there are no parts protruding from the mounting flange. It also allows for the best angle of view.

Additional Information

Additional Information

 N/A CeramTec's precision-engineered Ceramaseal® viewports are available with a choice of two viewport materials: sapphire or fused silica. Other viewport materials are available upon request.

CeramTec offers a UV grade fused silica viewport with a 1.37" view diameter that can be used for cryogenic applications.

Sapphire should be used in the most demanding applications, as this material provides extended transmission, temperature, pressure and wear resistance.

To select the right window for your applications, you should consider size, transmission requirements, temperature, pressure, and aggressiveness of environment.
