Adjustment-facilitating high-precision profile reference transmission device

Abstract

The invention relates to an adjustment-facilitating high-precision profile reference transmission device. The problem that angle adjustment of an existing profile reference transmission device is onlyrealized by a grinding mode which causes inconvenience in control of a grinding amount, low precision and relatively high grinding cost is solved. The device comprises a prism seat, an adapter plate,a prism base and a fine adjustment jackscrew, wherein the adapter plate comprises a first connection plate and a second connection plate; the first connection plate and the second connection plate are connected through a flexible component; a locating groove is formed in the side surface of the second connection plate; a first boss, a second boss, a first groove and a second groove are arranged on the prism base; a thread hole is formed in the second boss; the prism seat is arranged above the adapter plate; the second adapter plate is fixedly connected with the prism seat; the adapter plate is arranged between the first boss and the second boss; the first connection plate is fixedly connected with the prism base; the fine adjustment jackscrew penetrates through the thread hole of the second boss and presses into the locating groove of the second connection plate tightly.

Description

technical field [0001] The invention relates to precision optical adjustment equipment, in particular to a high-precision surface-to-surface reference transmission device that is convenient for adjustment, and is especially suitable for optical equipment with small external dimensions and high measurement accuracy. Background technique [0002] The surface-to-surface reference transmission device is a very important device in precision optical equipment. The surface-to-surface reference transmission device can well solve the problem that it is difficult to determine the surface-to-surface orientation in a small space, but the prism of the existing reference surface-to-surface device The base is integrally connected with the prism seat, and the adjustment of the angle between the optical axis of the prism and the normal line of the structure's backing surface can only be achieved by grinding the structure's backing surface. [0003] like figure 1 As shown, in the surface-to-...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of inconvenient control of the amount of grinding, low precision and high grinding cost caused by the grinding method in which the angle adjustment of the existing face-to-face reference transfer device is realized, and to provide a high-speed grinding machine that is easy to adjust. Accuracy surface reference transmission device, which can fine-tune the angle formed by the virtual optical axis of the prism and the surface of the prism, reduce the error, and make it reach the ideal design angle θ1
