The rugged, bonded construction of the calcium fluoride viewports allows bake-out to a maximum of 120 °C with ultra high vacuum (UHV) performance whilst the window offers extended broadband optical transmission from deep UV to the infrared. Specially coated optics optimised to minimise reflecance at customer specified wavelength can be quoted on request.
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.
