① The spectrum band is determined by the optical grating

② It can be adjusted depending on customers requirement

Spectrum band:

Optical resolution：

① Optical resolution means full width at half maximum (FWHM)
②Optical resolution is a synthesis result of light path design, wavelength and pixel density of detector
③ all the parameters of FSM spectrometer are tested values according to various influent factors and ensure the testing effect for customers.

④the width of slit has several options (10,25,50,100,200um）

① SNR usually means the signal noise ratio when spectrum has saturated  value

②The higher SNR, the stronger ability to gain signal

③Based on the progressing R&D, one advantage of FSM spectrometer is high signal noise ratio
