摘要
本文提出一种单片式二向色性窄带红外偏光镜,在特定波段,该器件具有接收角大、偏光参数在一定范围内连续可调等优点。片厚1mm时,在3.35～3.55μm和3.8～4.1μm消光比和透射比优于其他任何类型的偏光器件。
Infrared dichromatic polarizer made of thin calcite for narrow band is developed, which are of high transmittance high extinction ratioes and larger acceptance angles in certain regions. Their extinction rat'o and transmittance are better than those of any other polarizing devices in the wavelength range of 3.35-3.55μm and 3.8-4.1μm for the plates of 1mm thickness.
