The BRAP11 High Tolerance Right-Angle Prism is precision polished to tight tolerances for more demanding applications. This uncoated, N-BK7 prism dimension is 0.2 x 0.2 x 0.2 inch (5.0 x 5.0 x 5.0 mm). It has a λ/8 surface flatness and a 40-20 surface quality. This prism is recommended for general laboratory use in the visible range. 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.

BRAP11高公差直角棱镜是精密抛光，紧公差更苛刻的应用。这个没有涂层的N-BK7棱镜尺寸是0.2 x 0.2 x 0.2英寸(5.0 x 5.0 x 5.0 mm)。它有一个λ/ 8表面平整度和40-20表面质量。这种棱镜建议在可见光范围内的普通实验室使用。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。
