直角棱镜
 
特征
l 尺寸范围：3mm-60mm
l 材质为N-BK7或UV熔融石英
l 10mm和20mm的N-BK7棱镜可以在斜面或直角面上镀增透膜
高精度N-BK7和UV熔融石英直角棱镜可以使光路偏转90°或180°，光路偏转的角度取决于以棱镜的哪个面做为入射面（如下图所示），棱镜的尺寸从3毫米到60毫米可选。10毫米和20毫米N-BK7棱镜的斜面或两个直角面可以镀下面三种标准宽带减反射膜中的一种（A：350-700纳米，B：650-1050纳米，C：1050-1620纳米），这样可以有效地减少表面损耗。
因为是全内反射（TIR），左上方的图演示了直角棱镜如何用作90°反射镜。当光从棱镜的一个直角面入射时，光线会在斜面的玻璃/空气界面处发生全内反射（TIR），并从另一个直角面出射。这种让入射光改变90°的性质，使直角棱镜成为镜片的合适替代品。
右图展示了直角棱镜如何用作180°反射镜。当光从棱镜的斜面入射时，光会在一个直角面的玻璃/空气界面发生第一次全内反射（TIR）。在经过另一个直角面时，发生第二次全内反射（TIR），最后以反向平行于入射光线的方向从斜面出射。如同反光镜，光路产生的180°偏移不受入射到棱镜的角度的影响。
