詳細(xì)資料

楔形棱鏡可用于單獨(dú)偏轉(zhuǎn)激光光束至一定的角度，或者將兩個楔形棱鏡組合在一起作為光束偏轉(zhuǎn)應(yīng)用。單個棱鏡可將入射光束偏移一定的角度，如果用屈光度測量的話就是一個屈光度，相當(dāng)于在1米的距離下偏移了1厘米.

兩個楔形棱鏡可用來作為變形棱鏡使用（用來校正激光管輸出的橢圓形光束），或者用來將光束在4θ范圍內(nèi)以各種角度偏折，θ是指單個棱鏡偏折的光。這種光束整形是通過分別旋轉(zhuǎn)兩個楔形棱鏡來實(shí)現(xiàn)的，典型用于成像中的光束掃描不同位置。

注意: 光束偏差以度數(shù)和屈光度表示。一個屈光度是在離棱鏡 1米 距離下 1 厘米的偏差。
