Abstract
A novel design of a tunable prism filter using two dense flint prisms for eliminating laser plasma lines in a Raman spectrometer is presente d. Angular dispersion, beam diameter of the laser beam and divergence of the plasma radiation are considered to select the optimal configura tion. A remarkable feature of the filter is its high transmission effi ciency. The performance of the filter is compared with that of commerc ial tunable grating filters.
