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
Based on a toroïdal grating design, the TGS (Toroïdal Grating Spectrograph) series are compact flat field spectrographs. In this design, both grating and detector are fixed, which allows achieving a very good stability and compactness. With a choice of three gratings (both master and replica) the TGS series covers a large VUV range from 9.5 to 170 nm.
The TGS300 is offered as standard, other models can be available upon request.
