TGS 300 Toroidal Grating Spectrograph Brochure
TGS300
Vacuum Spectrometer - Toroidal Grating Spectrograph, coming from Synchrotron technologies
Based on a toroïdal grating design, the TGS (Toroïdal Grating Spectrograph) series are compact flat field spectrographs. In this design, the grating is fixed, which allows achieving a very good stability and compactness. Detector slides over the 40 mm exit flat field of the spectrograph. 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.
