A device for detecting coaxial precision superposition of a multi-layer optical filter for laser measurement

Abstract

This invention discloses a coaxial precision stacking device for multi-layer optical filter detection in laser measurement, belonging to the technical field of auxiliary equipment for optical filter detection. The device includes a main body with a height adjustment mechanism, a filter positioning and clamping mechanism, an adjustment mechanism, and a linked flipping mechanism. The adjustment mechanism employs a dual-operation mode with a main knob and a sub-knob. The main knob drives the flipping mechanism to switch positions, while the sub-knob, via bevel gear transmission, drives the flipping mechanism to precisely lift the filter. The filter positioning and clamping mechanism achieves flexible clamping through an elastic rubber ring and an annular gap, ensuring suspension stability. The height adjustment mechanism can quickly calibrate the reference height. This invention, through the coordinated linkage of multiple mechanisms, achieves precise coaxial stacking of multi-layer filters without manual intervention, combining ease of operation, positioning accuracy, and filter protection, significantly improving stacking efficiency and detection reliability, and meeting the multi-layer filter stacking requirements before optical detection.
