KF Flanged Kodial Glass Viewports

These KF 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).

KF Flanged Viewports Feature:

  • Made from 304 stainless steel and kodial glass
  • Standard KF style fluorocarbon o-ring used to affix to chamber
  • Due to the performance of fluorocarbon o-rings, the maximum temperature allowed is 200°C

NOTE: All viewports are fragile and should be handled and mounted with extreme caution. Never scratch the viewing area-a weakened viewport may implode (or explode under wrong conditions). Make sure the "glass" chosen has a reasonable transmission at the wavelengths of interest. And remember, what is not transmitted may be reflected or absorbed.
