Paper Abstract

Low polarization beamsplitter has been reported by article and patent in Applied Optics in 1983. Which structure is a quartz birefringent plate, it can be used to splite beam by using the reflection and refraction of the surface of the birefringent plate. In this article I have introduced a polychromatic adjustable beamsplitting angle low polarization prism, which is composed of four elements. I have studied it by theoretical analysis and experiment measurement. Whose character is: (1) the beamsplitting angle can be adjustable continuously, (2) transmission is high, (3) the intensities of the two beams are about equal, and, (4) the adjusting is convenient and reliable. Such as a 37 degree(s) prism, the beam splitting angle is from 15 degree(s) to 45 degree(s), transmission is above 85%, the maximum polarization degree of the emergent light is below 10%. The range of the beamsplitting angle can be designed in need.
