Abstract

In this paper, by using the matrix optics, the transmission of quartz crystal birefringent filter with any direction of incidence angle, azmuth, mechanical rotation angle was derived. Through theoretical simulation obtained the laws of central wavelength and free spectral range of quartz crystal birefringent filter changing with the mechanical-angle .The results show that when rotated around the z-axis of the filter mostly influenced the features of the filter and the transmission spectrum of the designed filter is tested and investigated by using Ultra-6600 spectrophotometer. The experimental results are in good agreement with theoretical results and it is helpful for manufacturing, adjusting and designing of the quartz birefringent filter.

 

Keywords: Optical devices, crystal optics, mechanical-angle, quartz crystal birefringent filters
