        格蘭泰勒棱鏡

         

        是由兩片相同雙折射晶體材料棱鏡制成的偏光器件,中間采用空氣隙結構。此棱鏡的長度與通光孔徑的比值小于1.0, 使之成為相對較薄的偏光器件。此棱鏡無逃逸窗口,因此適用于中低功率系統。由不同材料制成的格蘭泰勒棱鏡,其接收角各不相同,以下列表有相對應參數可對比。

        產品特點:

        ·空氣隙

        ·帶寬覆蓋紫外,可見和中紅外

        ·接近布儒斯特切割角

        ·無逃逸窗口,反射光線被吸收,適用于中低功率系統

        ·高偏振度

        ·長度短,緊湊
