Simulation and Analysis of Spectral Response Function and Bandwidth of Spectrometer

Figure 2

Monochromatic image by full aperture geometrical ray tracing. (a) 300.0 nm; (b) 632.8 nm; (c) 1500.0 nm; (d) 2500.0 nm. The area enclosed by the outer two horizontal and two vertical dashed lines represents the 0.3 mm × 7.0 mm exit slit. The filling factor along the dispersion direction decreases slightly as wavelength increases. Ray-tracing method considers aberrations but not the diffraction effect.
