In addition to our fiber-coupled cells, Wavelength References also offers bare absorption tubes. These tubes are useful for free space optical applications, such as those that require wavelengths where optical fiber is not applicable. We have many gases available and can provide mixtures as well. For example, our customers often request a backfill of nitrogen to mimic atmospheric conditions.
Tubes are made custom to order so several configurations are possible. When requesting an absorption tube, you may refer to our handyAbsorption Tube Info Sheet. Of course, please contact us with any questions. We’d be eager to hear about your application!
