Binary optical lens with high dispersion and high refractive index

Abstract

The invention discloses a binary optical lens with high dispersion and high refractive index. The binary optical lens comprises a lens experiment bearing platform and a chromatography laying clampingstructure, binary optical lens height adjusting mechanisms are arranged on the two sides of the upper end of the lens experiment bearing platform, one side of each binary optical lens height adjustingmechanism is connected with a binary optical lens angle adjusting structure, the chromatography laying clamping structure is arranged behind the binary optical lens, angle scale marks are arranged onthe surface of the binary optical lens angle adjusting structures, and a lens angle locking structure is arranged on one side of each angle scale mark. After polychromatic light enters the binary optical lens, because the binary optical lens has different refractive indexes for light with various frequencies and the propagation directions of the polychromatic light have different degrees of deflection, the polychromatic light is respectively dispersed and forms a spectrum when leaving the binary optical lens, so that the spectrum can be compared with the arranged spectrum, and the use convenience of the binary optical lens can be improved.

Description

technical field [0001] The invention relates to the technical field of binary optical lenses, in particular to a binary optical lens with high dispersion and high refractive index. Background technique [0002] Binary optics is a new branch of optics developed based on the theory of light wave diffraction. It is a frontier discipline formed by the mutual penetration and intersection of optics and microelectronics technology. The planar relief binary optical device based on computer-aided design and micron-level processing technology has the characteristics of light weight, easy replication, and low cost, and can realize new technologies such as miniaturization, array, integration, and arbitrary wavefront transformation that are difficult to achieve with traditional optics.
