Vacuum Ultra Violet Spectroscopy
There are several names given to wavelengths below the Ultra Violet. However, because of the absorption of the air down to few nanometers, and the need to evacuate any part of the environmental
The VHR spectrometers series are the Far UV version of our famous FHR series. Especially designed with an optical cavity which keeps pressure up to 10-5 mbar, the VHR series can extend spectral measurements down to 100 nm and up to MIR (15 µm) with optimal performances. As our FHR, the VHR series offer a unique combination of drive speed, precision and high resolution, completely revolutionizing the large spectrometer market.
