Diffraction gratings

While choosing a device configuration it is important to select properly the diffraction gratings. A right selection of the diffraction grating allows one to obtain the best combination of high energetic efficiency and spectral resolution.

The basic grating parameters, which determine the right choice of the diffraction grating, you can find in our methodical material “Spectral Instrument. Basic Concepts and Characteristics.”

We propose a wide range of diffraction gratings to be used in the NP250-2M two-channel Imaging spectrograph. Please, choose a necessary grating from the given below list, or consult our specialists.
