ISO Flanged Zero Length Kodial Glass Viewports

These zero-length ISO flanged glass viewports are manufactured from 304 stainless steel and Kodial glass. Viewports can be used to: let the operator view a process; initiate chemical or physical action using specific wavelengths; make measurements of emissions occurring in a process; or to monitor the effects of specific wavelengths (ellipsometry).

ISO Flanged Zero-Length Viewports Feature:

  • Offer a relatively large distortion-free viewing area with no interior voids that might create virtual leaks or dirt traps
  • Optical discs are commercial grade and fully annealed
  • Kodial glass (alkali borosilicate 7056)
  • Glass is sealed to a Kovar® transition piece before welding to the 304 stainless steel flange
  • Due to the performance of fluorocarbon o-rings, the maximum temperature allowed is 200°C

NOTE: It is strongly recommended that the user read the Technical Notes at the beginning of this section before baking any viewport.
