VHR Series

Vacuum Spectrometer - Vacuum High Resolution monochromators for the 100-1500 nm region

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.
