Viewport DN100CF, Standard 7056 Kodial (Borosilicate) Glass

Product code: VPCF100 Special Offer

The standard range of viewports mounted on CF, ISO-KF & ISO-LF flanges employ 7056 Kodial glass as the window material. The window itself is sealed into a Kovar® carrier which is subsequently welded into the host flange. Due to the Kovar® alloy standard viewports are magnetic. Standard viewports can be baked to a maximum of 400°C (dependant upon host flange). Due to differing coefficients of thermal expansion of the materials used in construction, a maximum temperature gradient of 3°C per minute should be adhered to during heating and cooling.

General purpose for HV & UHV applications.
Broad transmission range.
Bakeable to 350°C.
Lead Glass shielded versions available.
Non-magnetic versions available.
