Reference Spectroscopic Cells
We offer high quality reference spectroscopic cells available with a wide selection of high purity atomic and molecular fillings and buffer gases, each with a specific absorption spectrum. These reference spectroscopic cells are used in spectroscopic analysis for applications such as tunable diode laser and wavelength meter calibration and laser frequency stabilisation.
The reference spectroscopic cells can be Pyrex or Quartz and are available in the following materials and configurations:
- Borosilicate with flat windows attached parallel or angled
- Quartz with flat, high-quality fused silica windows attached parallel or angled
- Quartz with wedged, high-quality fused silica windows attached parallel or angled
- Quartz with flat, anti-reflective (AR) coated high-quality fused silica windows attached parallel or angled
The purity level of the natural elements used in manufacturing all wavelength reference spectroscopic cells, is greater than 99% and is distilled to an even higher purity during the filling process. All spectroscopic cells are helium leak checked and baked under vacuum to the 10-8 Torr range for a minimum of 24 hours, before they are filled with the selected element.
Vapour Reference Spectroscopic Cells
The vapour reference cells can contain natural Rubidium (Rb), Rubidium Isotope 85 or 87, Caesium (Cs), Potassium (K), Sodium (Na), Iodine (I) and Water.
The vapour reference cells can also be provided with a buffer gas of Helium, Xenon, Argon, Nitrogen or Neon gases, at a pressure of your specification
Gas Reference Spectroscopic Cells
The gas reference cells can contain Acetylene (Isotope 12 and 13), Krypton, Hydrogen Cyanide (Isotope 12 and 13), Carbon Monoxide (Isotope 12 and 13) and Methane.
Hazardous goods regulations
These wavelength reference spectroscopic cells are subject to hazardous goods regulations and must be shipped separately using specifically regulated shipping methods which will require special shipping and handling charges. Next day delivery is not available and the goods cannot be returned.
