Description

Technical Field

[0001] The utility model relates to the technical field of grating equipment, and more specifically to a grating lens fixing bracket with stable assembly. Background Art

[0002] A grating is an optical element used to separate and analyze spectra. It is composed of a series of parallel and equally spaced protrusions or depressions that can disperse the incident light into light of different wavelengths. Gratings can be used in various optical devices such as spectrometers, lasers, interferometers, microscopes, etc. The working principle of a grating is that when light passes through a grating, it is reflected or transmitted on the surface of the grating and dispersed into light of different wavelengths. The angles of these light rays depend on the spacing of the protrusions or depressions of the grating, that is, the grating constant. Therefore, depending on the grating constant, light of different wavelengths can be selectively separated. Gratings have a wide range of applications in scientific research, medical diagnosis, communication technology and other fields. For example, in astronomy, gratings can be used to analyze the spectra of stars to determine their chemical composition and temperature; in medicine, gratings can be used in optical computed tomography (OCT) technology to help doctors observe fundus lesions; in communication technology, gratings can be used to separate and merge different wavelengths of light to achieve fiber optic communication.

[0003] The grating is composed of a grating lens and a bracket for fixing the grating lens. In the prior art, the bracket for fixing the grating lens is usually composed of multiple bracket bodies. In a high-impact and vibration environment, the multiple bracket bodies are more likely to become loose, which may affect the working effect and reliability of the grating and may even cause the grating to fail.
