The 10BR08 Precision Right-Angle Prism is precision polished to tight tolerances for more demanding applications. This uncoated N-BK7 prism is 1 x 1 inch (25.4 x 25.4 mm) and 1 inch (25.4 mm) thick. It has a λ/4 surface flatness and a 20-10 surface quality. It is recommended for general laboratory use. By means of total internal reflection (TIR), a right-angle prism may be used as a 90° reflector or as a 180° retroreflector. Except for reflection losses from the entry and exit faces, TIR exhibits 100% reflectivity over a very large wavelength range.

10BR08精密直角棱镜是精密抛光，严格的公差，更苛刻的应用。这个未涂层的N-BK7棱镜是1 x 1英寸(25.4 x 25.4毫米)和1英寸(25.4毫米)厚。它有一个λ/ 20 - 4表面平面度和表面质量。建议一般实验室使用。通过全内反射(行动),可以使用一个直角棱镜作为90°反射器或180°反光镜。除了入口和出口面上的反射损失外，TIR在非常大的波长范围内表现出100%的反射率。
