The Photonics Technologies Potassium Reference Spectroscopic cells are available with Pyrex or Quartz windows and with high purity Potassium filling.
The Potassium Reference Cells come in a range of sizes, styles, and window materials.
Please see the ‘options’ tab in the table below for more details
Double-side anti-reflective (AR) coated windows are only available on spectroscopic cells made from quartz, with quartz or fused silica windows. The AR coating centered at 780nm has a wavelength range from 730 to 830 nm 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.
