Reference Spectroscopic Cells
Reference Spectroscopic Cells
At Photonics Technologies, we supply a wide range of high quality reference spectroscopic cells.
Our gas cells contain vapours of atomic elements or molecular compounds, each of these gas cells has its own specific absorption spectrum.
Our range of cells is each available with a wide selection of high-purity atomic and molecular fillings and buffer gases.
These gas reference cells are often used in spectroscopic analysis and applications which include: calibration of wavelength meters, laser frequency stabilisation, and tunable diode laser calibration.
Photonics Technologies offers reference cells that are made from Pyrex or Quartz, and come in a range of available configurations. Alternatively, if you require a different reference cell configuration please get in touch, custom reference cells can be manufactured to suit your requirements.
The cells can be made from Pyrex or Quartz. They 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 cells is greater than 99%.
All Photonics Technologies cells are helium leak checked and baked under vacuum to the 10-8 Torr range. This is done 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.
Our 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 (Isotopes 12 and 13), Krypton, Carbon Monoxide (Isotopes 12 and 13) and Methane.
Hazardous goods regulations
The Photonics Technologies Reference Spectroscopic Cells are subject to hazardous goods regulations. They must be shipped separately, using specifically regulated shipping methods that require special shipping and handling charges.
Please note, that next-day delivery is not available, and the goods cannot be returned.
