Precise orientation and assembly of Solc filter plates V.I

In this paper, we compare modulation and nonmodulation ways of orientating crystal plates of the Sole filter. A testing unit for modulation orientation of plates with their simultaneous assembly into the optical filter stack has been developed. We analyse possibilities of orientation at different phase shifts of a controlled plate as well as the influence of light source emission bandwidth and accuracy in setting optical elements on the output signal. A device for assembling crystal plates into the unified stack of the Solc filter has been designed.
