Optical Axis Positioning System for Middle Hole Lens

Abstract

The invention relates to a system and method for locating a mesopore lens optics optical axis. According to the structure of the system for locating the mesopore lens optics optical axis, a posture adjustment tool is arranged on a main shaft of a rotating lathe, a lens frame is arranged at one end of the posture adjustment tool, a mesopore lens is arranged in the lens frame, the B-side sphere center of the mesopore lens faces towards a first internal focusing telescope and a second internal focusing telescope, light which is emitted by the first internal focusing telescope passes through the A-side sphere center of the mesopore lens, light which is emitted by the second internal focusing telescope passes through the B-side sphere center of the mesopore lens, the light emitted by the first internal focusing telescope and the light emitted by the second internal focusing telescope are required to cover an entity of the mesopore lens as much as possible, and both the first internal focusing telescope and the second internal focusing telescope deviate from the axis where the A-side sphere center and the B-side sphere center are located. The system and method for locating the mesopore lens optics optical axis aims to solve the technical problem that no determining method of the mesopore lens optical axis exists in the prior art. By the complete adoption of the optics non-contact type measuring mode, the system and method for locating the mesopore lens optics optical axis guarantees the coincidence accuracy of the optical axis and the main shaft of the rotating lathe.

Description

technical field [0001] The invention belongs to the field of optical centering, and in particular relates to an optical axis positioning system for a center hole lens. Background technique [0002] As an optical component, lens plays a pivotal role in various aspects such as military affairs, astronomy, geography, and aerospace. With development, more and more attention has been paid to mesoporous lenses, but there is no method in the prior art that can accurately determine the optical axis of mesoporous lenses. [0003] When the lens has a large middle hole, due to the limitation of the focusing range of the inner focusing telescope, the field of view cannot cover the lens surface, that is, the light from the reticle of the inner focusing telescope passes through the middle hole of the lens. It is impossible to form a reflective self-collimating spherical image on the lens surface, such as figure 1 In the state shown, the optical axis of the aperture lens cannot be determ...
