Vacuum Viewport Manufacturing

Precision Fused Silica Viewports

Fused Silica vacuum viewports both have applications for high and ultrahigh facilities.

Constructed with high purity of silicon dioxide, 304 stainless steel and a vacuum tube-grade braze allows – allowing the viewports to meet 80% external transmission of 185nm.

Fused Silica is a polycrystalline, isotropic material, without a crystal orientation. The physical, thermal and electric properties allow all applications to uniform correctly.

Beneficial features:

  • Non-magnetic 304 steel, brazed seal
  • Resistant to thermal shock
  • Low loss ultraviolet transmission
  • High purity fused silica UV grade

 

Lowest Price on the UHV Viewport‎

moores-view-portsUHV viewports are widely used in the visual or broadband energy transmission in and out of UHV systems.

Properties of UHV that can be altered:

  •  Sealing type
  • The transmission performance
  • High temperature bake ratings
  • Vacuum leak rates

UHV viewports suit all clean UHV applications – due to a wide angle of vision, minimum transmission from bolts as well as maximum protection.

Quartz Optical Glass Viewports

  • Compatible with vacuum systems that are capable of reaching UHV levels
  • Leak rate: < 2×10 atm cc/sec He
  • Temperature range from -100 degrees to 200 degrees
  • Transmission of >90% at 250nm (externally)
