Description

Technical field: [0001] The invention belongs to the technical field of optical devices, and relates to a high-precision corner cube prism and a manufacturing method thereof. Background technique: [0002] A pyramid usually refers to any sharp corner of a cube, or a three-sided space cube corner composed of three mutually perpendicular square planes where the corner is located. The optical element of this kind of spatial structure is called corner cube prism, which has important applications in optics. The optical material is processed into a space cube with three sides perpendicular to each other. The light waves are reflected sequentially by the three inner surfaces of the cube to realize optical Retroreflection and optical polarization modulation effects to achieve special optical functions. Nevertheless, the processing of optical pyramids is extremely complex, requiring high precision and high cost. However, the machining technology is mature and the machining precisio...
