Viewport
Available in multiple material types and surface treatments to allow for the optimal transmission of specified wavelengths.
The optical disk used for viewing a process is commercial grade borosilicate glass such as 7056 or Kodial. For optical-critical applications, fused silica, quartz, sapphire, germanium are available. 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.

Shutter, bellow sealed
Viewport can become contaminated with the coating material. Shutter is used to prevent deposition onto the viewport, thus preserving the quality of viewport. Shutter can be locked in either open or close position.
Available in manual or pneumatic configuration.
