Reference Spectroscopic Cells
Reference Spectroscopic Cells
At Photonics Technologies, we supply a wide range of high-quality reference spectroscopic cells.
Our cells are filled with high-purity atomic elements or molecular compounds, each providing a distinct and well-defined absorption spectrum.
These gas reference cells are widely used in spectroscopic analysis and precision applications, including wavelength meter calibration, laser frequency stabilization, and tunable diode laser calibration.
We offer Pyrex and Quartz reference cells in a range of configurations. Some available materials and configurations:
- Borosilicate with flat windows attached parallel.
- 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, Krypton, Carbon Dioxide, Carbon Monoxide, Ammonia, and Methane.
Dangerous Goods Regulations
Some Reference Spectroscopic Cells are subject to Dangerous Goods Regulations. They must be shipped separately, using specifically regulated packaging and documentation that require special shipping and handling charges.
Please note, that next-day delivery is not available, and the goods cannot be returned.
