The Rubidium-85 Reference Spectroscopic Cells are available in Pyrex and Quartz with high purity Rubidium filling.
Double-side anti-reflective (AR) coated windows are only available on spectroscopic cells made from quartz, with quartz or fused silica windows. The windows are wedged and angled to avoid back reflections along the beam path and undesirable etalon effects. The AR coating centered at 780nm has a wavelength range from 730 to 830nm with a reflectance of less than 0.5%.
Pyrex vapour reference cells are not available with wedged windows, but Pyrex windows can be attached at an angle.
The Rubidium-85 Reference Cells come in range of sizes, styles, and window materials. Please see the Options tab in the table below for more details.
