Paper Abstract

We have designed and constructed a coded aperture spectrometer for use in the deep UV range. The Czerny-Turner design provides sufficient spectral resolution to observe Raman scattering features, while the use of a coded aperture provides a greatly improved light collection efficiency for scattering sources. The resulting instrument is capable of analyzing Raman spectra from samples at a 1 meter viewing distance. We provide an overview of the system, its optical design, and some preliminary measurements.
