NP250-2 Spectrograph

Close Menu
 


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

The basic grating parameters which determine their right choice you can find in the methodical material "Spectral Instrument. Basic Concepts and Characteristics."

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

 
SOL instruments: спектрометр, рамановский микроскоп, эмиссионный спектрометр. dif grating 435x315
