Windows (cover glasses) for polarimeter tubes

Bellingham + Stanley windows (or cover glasses) for our polarimeter tubes. Precision made using low strain materials to prevent any added optical rotation to the sample under test.  All windows are now manufactured using silica with a transmission bandwidth of 300-900 nm facilitating use with polarimeters operating in the UV, Vis or NIR spectrum.

XPC - 10mm diameter
UV/Vis/NIR for XPC metal (stainless steel) polarimeter tubes for use with polarimeter tubes 35-90, 35-91, 35-92 and 35-93.

Standard - 15.5mm diameter
UV/Vis/NIR for standard glass polarimeter tubes with nylon, stainless steel (metal) or PEEK endcaps including 35-10, 35-11, 35-12, 35-13, 35-17, 35-18, 35-28, 35-29, 35-30, 35-35, 35-45, 35-46, 35-47, 35-56, 35-57 and 35-58.

Low Volume - 20mm diameter
