The 10SR20 Precision Right-Angle Prism is precision polished to tight tolerances for more demanding applications. This uncoated fused silica prism is 1 x 1 inch (25.4 x 25.4 mm) and 1 inch (25.4 mm) thick. It has a λ/10 surface flatness and a 10-5 surface quality. For UV, infrared, or thermally sensitive applications fused silica prisms are advised. Our fused silica prisms are manufactured to exacting specifications and are useful from 185 nm–2.1 μm. 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.

10SR20精密直角棱镜是精密抛光,严格的公差,更苛刻的应用。这种未涂覆的熔融石英棱镜有1×1英寸(25.4×25.4毫米)和1英寸(25.4毫米)厚。它有一个λ/ 10表面平面度和纯表面质量。对于紫外线,红外线,或热敏感的应用熔融硅棱镜建议。我们的石英玻璃棱镜制造严格的规范,从185 nm - 2.1μm是有用的。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。
