Abstract

The invention discloses an assembly and adjustment method of a large-size collimator focal plane assembly, which is mainly used for fast assembly and adjustment of a reticle, a star point plate and a target plate in the large-size collimator focal plane assembly. The implementation steps of the method mainly include: 1. Preliminarily determining the position of the focal plane of the collimator, and installing a tooling substrate near the preliminarily determined focal plane; 2. Determining the corresponding focal positions of the collimator under different fields of view; 3. Install the tooling ball head assembly on each through hole, adjust the tooling ball head assembly to obtain the final focal plane position of the collimator; 4. Install the focal plane assembly of the collimator. The method of the invention can accurately mark the focal plane position of the collimator at one time, avoiding the cumbersome and time-consuming problem in the process of adjusting the focal plane assembly of the light tube by using the theodolite to measure the beam parallelism of multiple fields of view.

Description

technical field [0001] The invention relates to the technical field of optical system assembly and adjustment, in particular to a large-size collimator focal plane assembly assembly method, which is mainly used for reticle, star point plate, and target plate in the large-size collimator focal plane assembly Quick setup. Background technique [0002] The reflective optical system has attracted people's attention for a long time due to its advantages of no chromatic aberration, compact structure, and the ability to reduce the weight of large-aperture, long-focus telescopic systems, etc. . The image quality evaluation in the development process of this type of optical system is inseparable from the corresponding collimator with large aperture and long focal length. [0003] The collimator provides an infinite target or a beam of parallel light for the image quality inspection of the reflective optical system. Its basic structure is to place a reticle, a star point plate, a ta...
