Buying Diffraction Gratings

Diffraction gratings are optical devices with a periodic phase or amplitude structure. They are used in spectrometers and monochromators for wavelength separation and in ultrafast optics for stretching and compressing pulses. These gratings can be reflective or transmissive, depending on the application.
