Off-axis transmission spectrum of quartz rotation filter

Abstract: Off-axis transmission spectrum of quartz rotation filter is studied in this paper in detail through numerical simulation and experiment research, we find the central wavelength, band width and amplitude of output light will all change when the quartz rotation filter is rotated with a tilted angle, the central wavelength will change to a longer wavelength, band width and amplitude will decrease as the tilted angle increase. These results will be helpful to further explore the transmission character of quartz birefringence, rotation filter and relative applications, as we believe. [Copyright &y& Elsevier]
