CF Flanged Kodial Glass Viewports

These zero-length CF flanged glass viewports are available to suit a variety of applications. 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).

CF Flanged Kodial Glass Viewports Features:

  • UHV compatibility
  • Large, distortion-free viewing area without interior voids, minimizing trapped volume and particulate
  • Commercial grade optical discs of fully annealed Kodial glass (alkali borosilicate 7056)
  • Kovar metal transition piece between glass and CF flange
  • Bakeout to 350°C (heating rate should not exceed 2-3° per minute)

Notes:
  • 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.
  • For safety, we strongly recommend that no viewport is exposed to a temperature ramp of greater than 2-3°C per minute, and that no viewport be exposed to direct thermal radiation. To limit thermal gradients when heating viewports, we recommend the viewing area and the flange be covered with many layers of aluminum foil to act as a reflective shield.
