BEFORE You Begin, INSPECT THE VIEWPORT
Caution Required When Using Viewports
• Viewports are Rated for Vacuum NOT Pressure

• All viewports are fragile and must be handled and mounted with extreme caution

• NEVER use a viewport that appears to be, or is known to be damaged

• Never scratch the viewing area; a weakened viewport may implode (or explode) under wrong conditions.

• A faulty viewport can cause serious injury

• Make sure the glass chosen has a reasonable transmission at the wavelengths of interest.

• Remember, what is not transmitted may be reflected or absorbed.
