直角棱镜
直角棱镜（Right angle prism）被广泛应用于旋转图像和重定向输入光。它们可以作为镜子使光线偏离90度，也可以作为回复反射器，通过全内反射使光线偏离180度。它们是偏振和非偏振立方体分束器的主要部件。
福州光骅达光电有限公司（Photonchina）采用特殊选择的低散射、低吸收的光学材料，可以提供激光级的直角棱镜。标准尺寸的激光级直角棱镜，表面光洁度好，平面度高达L/10，精度高。
直角棱镜可选材料有：N-BK7、紫外熔融石英、CaF2、ZnSe或Ge。
我们根据客户要求提供镀膜或者不镀膜产品。
Right Angle Prisms
Right angle prisms (RAP) are widely used for rotating image and redirecting the input light. They serve as a mirror to deviate light through 90 degrees and also as a retro-reflector to deflect light through 180 degrees by total internal reflection. They are the main components for polarizing and non-polarizing cube beamsplitters.
Photonchina laser grade Right-Angle Prisms are fabricated by special selection optical materials with low scatter and absorption. Standard size laser grade right angle prisms, with good surface finish, flatness as high as l/10 and high accuracy are available in Photonchina.
Materials: N-BK7, UV Fused Silica, CaF2, ZnSe, or Ge。
Uncoated or AR coating requirements upon customer’s request.
