Full-wave-band high-precision zoom optical system image surface butt joint and coaxial adjustment device and method

Abstract

The invention provides a full-wave-band high-precision zoom optical system image surface butt joint and coaxial adjustment device and method, and solves the problems that an existing zoom optical lensimage surface adjustment method is low in efficiency, an imaging assembly is easy to damage, and the image surface adjustment precision is relatively low. The device comprises an optical platform, agrating ruler, a display, a light source, a full-waveband collimator, a zoom lens fixing mechanism and an image plane adjusting assembly, the full-waveband collimator is arranged on the optical platform; the zoom lens fixing mechanism is arranged on the optical platform through the four-dimensional adjusting platform, and the four-dimensional adjusting platform adjusts the position of a zoom optical lens on the zoom lens fixing mechanism; the image plane adjusting assembly comprises a CCD mounting frame, a four-dimensional adjustable base, a sliding block and a guide rail control assembly fordriving the sliding block to move; the CCD mounting frame is arranged on the four-dimensional adjustable base; the four-dimensional adjustable base is arranged on the sliding block; the grating ruleris used for recording the position of the CCD imaging assembly; and the display is connected with the CCD imaging assembly.

Description

technical field [0001] The invention relates to an image plane adjustment technology of a zoom optical system, in particular to a full-band high-precision zoom optical system image plane docking and coaxial adjustment device and method. Background technique [0002] At present, the commonly used zoom optical lens image plane adjustment method is to firstly design the thickness of the spacer according to the theory, combined with the difference in image clarity under the change of long and short focal lengths, through continuous research and iteration on the thickness of the spacer, determine the final thickness of the spacer, and complete the lens Image plane adjustment work. But for batch lens image plane adjustment, this method has the following disadvantages: [0003] 1. The gasket repair and research process is based on the theoretical design thickness, and according to the actual image clarity, manual repair and interpretation are performed, and the efficiency is low; ...
