Vapor Wavelength Reference Cells
Precision Glassblowing offers high quality vapor wavelength reference cells and gas cells for spectroscopy.
We carry the following vapor wavelength reference cells: Rubidium (Rb) cells, Cesium (Cs) cells, Iodine (I) cells, Sodium (Na) cells, Potassium (K) cells, Lithium (Li) cells, Thallium (Tl) cells, or Indium (In) cells. We also offer isotopically enriched Rubidium* cells (85 and 87) and Potassium* cells (40 and 41). The purity level of the natural elements used in manufacturing all vapor cells is greater than 99% and is then distilled to an even higher purity during the filling process. Upon request, we offer buffer gases like Helium, Neon, Argon, Krypton, Xenon, Nitrogen, and Ethane as well as paraffin coating and OTS coating.
All vapor cells are helium leak checked and then baked under vacuum to the 10-8 torr range before they are filled with the selected element.
Precision offers gas cells filled with Acetylene (Isotope 12 and 13), Hydrogen Cyanide (Isotope 12 and 13), Carbon Monoxide (Isotope 12 and 13), and Methane. All gases used in manufacturing process have a purity level greater than 99%.
All reference cells are available with optical quality borosilicate windows, quartz windows, high-quality quartz windows or anti-reflective (AR) coated high-quality quartz windows. Reference cells with wedge windows or Brewster angle windows are available upon request.
*Precision Glassblowing offers a reaction/distillation service for production of isotopically enriched Potassium and Rubidium. Contact us for more information.
