Larson Electronic Glass fused silica viewports are
preferred over glass because of their transparency to
ultraviolet radiation, higher abrasion resistance, and
low coefficient of thermal expansion which makes them
very resistant to thermal shock. While fused quartz and
fused silica viewports are both silicon dioxide (SiO2),
fused silica, which is synthetically grown, is superior
to a fused quartz viewport in most regards and does not
fluoresce when exposed to UV radiation at 253.7µm as
does fused quartz.
NOTE: Maximum bakeout temperature
limited to 200°C due to low temperature braze alloy.
Fused Silica viewports are offered with CF type, ISO
type Kwik-Flange® and Large-Flange®. Viewport window
surfaces offer a minimum of distortion and provide
maximum transmission for most applications.
Zero-Length offers greater distortion-free view area
