Abstract

In the present paper an optical scheme of compact two-element spectrometer for detection of fluorescence spectra is presented. It consists of a concave holographic grating and a spherical projection mirror. The working spectral range is 500-1000 nm and the spectral resolution reaches 0.91 nm. The scheme is extremely compact and has F/# equal to 2.4.The design procedure is described in details with special emphasis on stray light suppression. The developed scheme can be used in a small-sized affordable diagnostic device, which is of a special interest for cancer diagnostics.
