CF Flanged Quartz (Fused Silica) Non-Magnetic Viewports

CF Flanged Quartz (Fused Silica) Non-Magnetic Viewports Features:

Built from the highest-quality materials to UHV standards
Compatible with vacuum systems capable of reaching UHV levels
Viewports may be sealed with fully annealed copper gaskets to reduce induced strain
If the process deposits material, we strongly recommend a viewport shutter because deposits can damage and impair the optical properties of the lens.

Charts

UV & DUV Fused Silica Transmission Spectrum

Notes:

All viewports are fragile and should be handled and mounted with extreme caution. Never scratch the viewing area-a weakened viewport may implode (or explode under wrong conditions). Make sure the "glass" chosen has a reasonable transmission at the wavelengths of interest.
For safety, we strongly recommend that no viewport is exposed to a temperature ramp of greater than 2-3°C per minute, and that no viewport be exposed to direct thermal radiation. To limit thermal gradients when heating viewports, we recommend the viewing area and the flange be covered with many layers of aluminum foil to act as a reflective shield.
