windows for vacuum chamber |
|

I'm checking the properties/prices/availability of window for the vacuum chamber.
Plan1: 10" diameter window (6" window opening)
- A&N: ($775), no info on optical quality. This is probably just a regular viewport similar to the one we use.
- Pfeiffer also offers viewports for visually monitoring, so I think they are not good enough.
- MDC fused silica window, for 10" flange ($ 3,297), no optics properties. Only lens grade for ultraviolet are specified, but they claim that for IF also available (viewport)
- Nor-Cal also has flange for 10" and 2.75" with glass,fused quartz, fused silica material. no optics properties shown.
Plan2: 10" diameter blank with 2 smaller windows (1.5"/2" diameter)
- Thorlabs: 2.75" OD window, 1.18" window (windows are replacable, I think we can switch to CVI windows ) ($244 x2) + machining .
- MDC offer 2.73" with 1.5" window, no info on optics properties
Most of the manufacturers do not have good window for laser with 10" flanges. Finding two smaller windows with good optics properties is probably easier. |
