VIEWPORT,Z-L,LASER SERIES,4-1/2"UHV,DIODE 1550NM ONLY KJLC VERIFIED CLEANING PROCEDURE SHOULD BE UTILIZED ON THIS OPTICAL WINDOW SO AS TO ENSURE PRESERVATION OF SEAL INTEGRITY.

1.

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.

2.

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.

** O-ring seals normally cannot handle temperatures as high as the viewport itself **
