Please note that the optical reflectance curves are approximations and should be used for reference only.
Non-magnetic viewports are offered for low energy applications or surface science applications needing low magnetic fields. The non-magnetic viewports use a non-magnetic weld ring instead of the regular kovar weld ring. VacTechniche viewports are manufactured in clean room conditions and helium leak tested, cleaned and packed to UHV standards.
The rugged construction of the fused silica viewports allows epeated bake-out with UHV performance, whilst the window offers broadband optical transmis- ion through deep UV, visible to near infrared. Non-standard viewports can be manufactured on request, including re-entrant style microscope/camera viewports. Annealed copper gaskets and other component accessories are also supplied by VacTechniche.
