5. Grating and Wavelength Range (specify grating and starting wavelength): We
install the grating on a platform that we then rotate to select the starting wavelength
you have specified. Then we permanently fix the grating in place to eliminate
mechanical shifts or drift.
Use our online Range and Resolution Calculator to find out how your grating choice
affects spectral range and optical resolution by viewing the grating efficiency curves.
The available gratings are summarized below:
