Abstract
A tunable optical filter is described for removing undesired emissions from laser beams for use in resonance Raman and fluorescence spectroscopy. The bandpass is 1 nm, and the filter is tunable from 400 nm to 750 nm. The degree of polarization of the dye laser beam is improved by the filter. Two independent controls tune the filter to the selected frequency, while the input and output beam directions remain fixed.
