The BRAP13-AV High Tolerance Right-Angle Prism is precision polished to tight tolerances for more demanding applications. This protective aluminum coated hypotenuse, AR.14 Coated faces, N-BK7 prism dimension is 0.39 x 0.39 x 0.39 inch (10.0 x 10.0 x 10.0 mm). It has a λ/8 surface flatness and a 40-20 surface quality. Newport's AR.14 broadband IR antireflection coating is applied to the two prism legs and supports a 425 to 675 nm wavelength range. The antireflection coating reduces surface losses yet does not affect total internal reflection or the acceptance angle. 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.

BRAP13-AV高公差直角棱镜是精密抛光，紧公差更苛刻的应用。N-BK7棱镜尺寸为0.39 x 0.39 x 0.39英寸(10.0 x 10.0 x 10.0 mm)。它有一个λ/ 8表面平整度和40-20表面质量。Newport公司的AR.14宽带红外抗反射涂层应用于两个棱镜支架，支持425到675 nm波长范围。抗反射涂层减少了表面损失，但不影响全内反射或接受角度。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。
