Optical Design and Performance Evaluation of a Mini Spectrometer for Space Applications
The mini spectrometer design is discussed, and two models using finite elements approach are presented. The simplest optical design is used to reduce the optical signal losses. The two models considered are based on the use of transmission and reflection gratings respectively. The two designs are compared based on the obtained wavelength resolution. Our results showed that the spectrometer based on the transmission diffraction grating performed better and showed good wavelength resolution with a small footprint making it suitable for space deployment.
