Abstract

The invention relates to an optical reflection structure, and especially relates to the optical reflection structure for parallel optical path modification and a preparation method thereof, and a concave cambered surface reflection element. When a parallel optical path of a linear light source enters the reflection surface, a conventional reflection prism structure cannot change the parallel reflection optical path; the optical reflection structure can solve said problems. The optical reflection structure comprises the reflection surface; the reflection surface is a concave cambered surface; the concave cambered surface of the optical reflection structure can modify the linear light source into a non-parallel optical path, thus enabling the reflection optical path to form a deflection angle.

Description

technical field [0001] The invention relates to an optical reflection structure, in particular to an optical reflection structure for parallel light path modification, a preparation method thereof, and a concave arc surface reflection element. Background technique [0002] The cross-section of traditional triangular prisms is generally a standard triangular structure, or even a special equilateral triangle or isosceles triangle. Triangular prisms are generally used as optical structures in the following two ways: [0003] (1) The three sides corresponding to the three sides are all light-transmitting surfaces, which serve as an optical transmission structure. Usually, the refraction light path on two sides is used as a beam splitter, or the light path of reflection, total reflection, and refraction is used as a mirror, or the light path refracted upward on two sides is used as a condenser, or even a combination of two sides with a special 90° top angle as a retroreflector....
