Potassium Reference Cell Potassium Reference Cells

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.
