The BRP-12.7 ValuMax® Right-Angle Prism is ideal for beam bending and retro reflection applications. It is often used instead of mirrors in applications where deformation of the reflective surface may cause a problem. The fine balance between performance and cost has been optimized, making this prism ideal for OEM applications in the visible and near infrared. 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 broad wavelength range. The reflecting surface should be coated with protected aluminum if the incidence angle exceeds that acceptable for TIR or if the environment does not allow the reflecting surface to be kept clean, as TIR requires. The hypotenuse can also be used as a first surface reflector. In this case, the overcoat of black paint should be removed with acetone. This uncoated 1/2 x 1/2 inch (12.7 x 12.7 mm) prism is 1/2 inch (12.7) mm thick and can be conveniently mounted and positioned on Newport holders.

brp - 12.7 ValuMax®直角棱镜是理想的梁弯曲和复古的反射的应用程序。在反射面变形可能导致问题的应用中，它经常被用来代替镜子。在性能和成本之间的精细平衡被优化，使这个棱镜理想的OEM应用在可见光和近红外。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。除了入口和出口表面的反射损失外，TIR在非常宽的波长范围内表现出100%的反射率。如果反射表面的入射角超过TIR可接受的范围，或者环境不允许反射表面按照TIR的要求保持清洁，则反射表面应涂上保护铝。斜边也可以用作第一个曲面反射器。在这种情况下，黑色涂料的外套应该用丙酮去除。这是1/2 x 1/2英寸(12.7 x 12.7毫米)棱镜是1/2英寸(12.7)毫米厚，可以方便地安装和定位在新港持有人。
