Wavelength Calibration Artifacts
The WA Series of wavelength calibration references enable precise wavelength accuracy. Our WA Series of references utilize gas cells. Gas cells provide a feature set unavaiable from other reference technologies in terms of absolute long-term accuracy and environmental insensitivity. We offer configurations from mini gas cells to gas cells in instrument housing for a complete calibration solution.

Very Stable
The WA Series has very low temperature dependence of 0.01 pm per °C.

Safe
The concentration of gasses in these devices is extremely low. Even if the device were purposefully ruptured there is no danger. There are no restrictions on shipping these products because they ship under the small quantity exemption in compliance with the U.S. Department of Transportation.

Traceable Calibration
As an option, we can provide simultaneous sweep data via a NIST-verified reference cell to add confidence to the calibration information.
