Diffraction gratings
Diffraction gratings
A variety of short-focal-length diffraction gratings are available for original equipment manufacturers. The small gratings can be used in small imaging spectrographs with linear detectors at wavelengths from 380 to 760 nm. The miniature flat-field gratings range in focal length from 20 to 60 mm with f numbers from f/1.7 to f/3.6.
