Coated & metallized optics > Sapphire hermetic windows & Sapphire Vacuum windows

Sapphire windows with solderable and brazeable metallization can be sealed in high vacuum and hermetically sealed applications

Sapphire assemblies are sealed with solderable metallization or brazed for the higher pressure applications.

  • Hermetic and low pressure environmental protection sealing commonly done with solderable metallization combined with a range of end user specified solder options
  • Sapphire offers very high pressure performance with reasonable window thickness & weight based on the much higher strength of sapphire – 6X greater than glass, fused silica, or quartz.
  • Braze metallized sapphire viewports can be mounted in many standard vacuum and UHV flanges
  • High pressure assembly versions also possible with metal and elastomeric/O-ring sealing designs
