Laser Transmission Viewport
Available in multiple material types and surface treatments to allow for optimal transmission of specified wavelengths
Optical disk used for viewing only uses borosilicate glass such as 7056 or Kodial. For optical critical applications, fused silica, quartz, sapphire, Pyrex are used. Choose optical material that has a high transmission at the wavelength of interest.
Kodial viewport can withstand repeated bakeout cycle to 350° C. However, to avoid thermal stress, the heating rate should not exceed 2 deg. per minute. Finger-tight the bolts; use cross-flange tightening pattern, and never rotate any particular bolt more than 1/8 turn at a time.
UV grade fused silica viewports has a bakeout temperature of 200°C. Sapphire Viewport has a bakeout temperature of 450°C.
Pyrex Viewports provide a convenient and economical solution for vacuum systems requiring periodic glass subtrate replacement. Applications like vacuum coating will deposit materials on viewports which will eventually render them useless. The Pyrex substrate is sealed against an gasket and clamped in place with an aluminum flange which prevents metal to glass contact.
