The BPP-12.7 Penta Prism deviates a line of sight or input beam by precisely 90°. In imaging applications the penta prism will neither invert nor reverse the image. This prisms deviate a beam through the same angle regardless of its orientation to the beam. This makes penta prisms valuable for applications requiring an exact 90° deviation without having to orient the prism precisely. The monolithic design of a penta prism also makes it inherently more stable than a system consisting of two mirrors. This 0.5 x 0.5 inch (12.7 x 12.7 mm) prism is 0.5 inch (12.7 mm) thick. The geometry of these prisms requires the reflecting surfaces to be coated. The reflecting surfaces of our penta prisms are coated with protected aluminum with a black paint overcoat. The entrance and exit faces are uncoated but can be antireflection coated. Please contact Newport if you require an antireflection coating.

bpp - 12.7五棱镜偏离视线或输入光束精确90°。在成像应用中，五棱镜既不会反转也不会反转图像。无论光束的方向如何，这个棱镜都会使光束偏离相同的角度。这使得五棱镜有价值的应用程序需要一个精确的90°偏差而无需东方棱镜精确。五棱镜的整体设计也使它天生比由两个镜子组成的系统更稳定。这个0.5 x 0.5英寸(12.7 x 12.7毫米)的棱镜是0.5英寸(12.7毫米)厚。这些棱镜的几何形状要求反射面的涂层。我们的五棱柱的反射表面涂上了保护铝与黑色涂料大衣。入口和出口表面没有涂层，但可以进行抗反射涂层。如果您需要一层抗反射涂层，请与新港联系。
