Abstract

A solar filter assembly combines a high-precision Fabry-Perot etalon (22) with a variety of conditioning filters (26,28,32) judiciously selected to effectively block completely all radiation except for the spectral line of interest. In addition, a tuning mechanism (36) is provided to precisely control the peak frequency of the filter's output by varying the optical length of the etalon's cavity.
