Abstract

The invention belongs to the technical field of optical prisms, and particularly relates to an optical device for measuring wavelength. The optical device comprises a cavity provided with a peripheral wall, an upper cover plate and a lower cover plate, at least two prisms in the shape of triangular prisms are arranged on the lower cover plate of the cavity, prismatic columns corresponding to the prisms are arranged inside the cavity and on the inner surface of the lower cover plate, and to-be-measured light is enabled to form light only having different optical paths for measuring after passing the prisms, the lower cover plate, the prismatic columns and the upper cover plate. By the optical device, the problems of high-precision control in laser direction and repeated demounting for maintaining and debugging can be solved. The optical cavity can be applied in high-precision measuring of spectra having pulse laser or continuous laser wavelength and analysis. Precision of the optical cavity in measuring laser wavelength can reach 1X10-7, and the optical device has the advantage of convenience in use.

Description

technical field [0001] The invention belongs to the technical field of optical prisms, in particular to an optical device for measuring wavelengths and a control method thereof. Background technique [0002] The current device for changing the laser direction has a large precision control error and the control method needs to be repeated many times, especially the optical cavity of its core product is the core optical component of the laser wavelength meter instrument. The wavelength meter is the only instrument that can accurately measure the value of the laser wavelength by means of optical measurement. Products are widely used in scientific research, optical communication and industrial fields. As a whole, the designed wavelength meter and the current optical cavity cannot be used for high-precision measurement of the spectrum and analysis of pulsed laser or continuous laser wavelength. [0003] Therefore, how to develop an optical device for measuring wavelengths, avoi...
