Larson Electronic Glass zero length sapphire windows
allow the window to be mounted as close to the chamber
as reasonably possible and allow the clearest access
from the window surface on the air side. These zero
length windows are silver-brazed to Kovar® sleeves. They
are mounted in stainless steel tube-weld adapters and CF
type flanges for use below 1x10-11, or ISO
type Kwik-Flange®. Optional flange weldments are
available as special order.
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.
Larson Electronic Glass offers "Zero-Length Sapphire
Viewports" available in 4 standard sizes from 3/4 inch
through 2 inch with a variety of flange options.
Dimensions are in inches unless otherwise noted.
