Abstract
The optical system that can measure spectra in the deep UV wavelength range with high sensitivity and focus laser beams was designed using ray tracing to develop a LIDAR system for resonance Raman spectroscopy for remote detection of trace amounts of hazardous substances. The single Cassegrain-type telescope for focusing the laser beam and scattered light was used to achieve a high overlap between the fields of view of the laser beam and the optics receiving the scattered light. The simulation results showed that the laser beam and scattered light could be imaged with small aberrations.
