    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(jié)構(gòu)。此棱鏡的長(zhǎng)度與通光孔徑的比值小于1.0, 使之成為相對(duì)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(tǒng)。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(duì)應(yīng)參數(shù)可對(duì)比。

    產(chǎn)品特點(diǎn):

    ·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(tǒng)

    ·高偏振度

    ·長(zhǎng)度短,緊湊
