A study on suppressing transmittance fluctuations for air-gapped Glan-type polarizing prisms
Optics Communications(2018)
Abstract
Light intensity transmittance is a key parameter for the design of polarizing prisms, while sometimes its experimental curves based on spatial incident angle presents periodical fluctuations. Here, we propose a novel method for completely suppressing these fluctuations via setting a glued error angle in the air gap of Glan–Taylor prisms. The proposal consists of: an accurate formula of the intensity transmittance for Glan–Taylor prisms, a numerical simulation and a contrast experiment of Glan–Taylor prisms for analyzing the causes of the fluctuations, and a simple method for accurately measuring the glued error angle. The result indicates that when the setting glued error angle is larger than the critical angle for a certain polarizing prism, the fluctuations can be completely suppressed, and a smooth intensity transmittance curve can be obtained. Besides, the critical angle in the air gap for suppressing the fluctuations is decreased with the increase of beam spot size. This method has the advantage of having less demand for the prism position in optical systems.
