Right-Angle Prism, N-BK7, 12.5 mm, λ/8, Uncoated
Model: BRAP14
Product Series Overview
Standard N-BK7 Right-Angle PrismsThe BRAP14 High Tolerance Right-Angle Prism is precision polished to tight tolerances for more demanding applications. This uncoated, N-BK7 prism dimension is 0.49 x 0.49 x 0.49 inch (12.5 x 12.5 x 12.5 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.
