Description

Technical Field

[0001] The utility model relates to the technical field of optical calibration equipment, in particular to a two-axis three-mirror reflection portable optical calibration equipment. Background Art

[0002] Optical calibration equipment is a tool used to calibrate optical systems, instruments or equipment. Its main function is to ensure that the position, angle and performance of each optical element (such as lens, lens, prism, etc.) in the optical system meet the design specifications and requirements. Optical calibration usually includes adjusting and calibrating the focal length, resolution, distortion, chromatic aberration and other parameters of the optical system to ensure that the optical system can accurately capture, transmit and process optical signals or images. Optical calibration equipment usually includes components such as light sources, detectors, adjustment devices and analysis software to achieve comprehensive calibration and adjustment of optical systems. These devices can be used in various application fields, such as industrial manufacturing, medical imaging, aerospace, unmanned vehicles, etc., to ensure that the performance and accuracy of the optical system meet the required standards. The two-axis three-mirror reflective portable optical calibration equipment is a portable device for calibrating optical systems. Its design is based on the reflective optical structure of two axes and three mirrors. The two-axis three-mirror design greatly reduces the system volume through three-fold return without changing the optical path. The three mirrors can eliminate third-order spherical aberration, coma and astigmatism through the distribution of optical focal length and aspheric design. The primary mirror and the secondary mirror form a focus between them, which is the primary image plane of the system. A 45° plane folding mirror is set at the primary image plane to reflect the light to the third mirror, and then the image is formed on the image plane through the three mirrors.

[0003] When cleaning dust on the surface of the internal optical lens, the existing two-axis three-mirror reflection optical calibration device is usually disassembled by screwing the threads, which is cumbersome to operate, not portable, and affects the work efficiency of the staff.
