Standard Length Sapphire Viewports

Larson Electronic Glass standard length viewport is available in a 5/8” nominal view. The length of the weld sleeve dictates that it be mounted as a standard length window as opposed to the zero length.  Windows are silver-brazed to a Kovar® sleeve. They are offered as weldable, in CF type flanges for use below 1x10-11, or ISO type Kwik-Flange® or for intermediate vacuum ranges.

Sapphire Window surfaces which are extremely hard and scratch resistant offer a minimum of distortion and provide maximum light transmission suitable for most applications. UV grade viewports have a 90° crystal orientation normal to the optical axis.

Features:

  • Available in 5/8” only
  • UV grade.
  • >80% Transmission from 250nm to 4000nm
  • CF and Weld mount bakeable to 450°C, 25°C/Min gradient
  • Kwik-Flange® bakeable to 200°C

Larson Electronic Glass offers "Standard Length Sapphire Viewports" available in 1 standard size of 5/8 inch with a variety of flange options. Dimensions are in inches unless otherwise noted.
