Demountable Glass and Quartz Viewports

Accu-Glass’ demountable high transmission glass and quartz viewports are an economical “alternative” to typical ­fused glass or brazed quartz viewports. Transmission is greater than 90% over the 350nm to 1500nm wavelength range. Removable Accu-Sol™ glass and quartz substrates allows for subsequent application of optical coatings and viewport cleaning. For high temperature applications up to 250°C, Kalrez® elastomer O-ring seals are recommended. Demountable substrate viewports employ a unique ­recessed zero profile design... providing the widest viewing angles and maximum protection to glass and quartz substrates.
