Integral bidimensional optical adjusting frame

Abstract

The invention provides an integral bidimensional optical adjusting frame, which comprises an adjuster; two parallel slits of which the opening directions are vertical mutually are formed at the 1 / 3 part and the 2 / 3 part of the integral adjuster; fastening sheets are arranged on the top face and one side face of the adjuster respectively; a lens is fixed in the centre of the front face of the adjuster through a lens compression ring; two adjusting screw rods are arranged on the back face of the adjuster; the two adjusting screw rods are respectively positioned on the opened sides of the two slits of the adjuster; a pressure spring is arranged in the middle of each slit; and the pressure rings are sleeved on the adjusting screw rods. The integral bidimensional optical adjusting frame has the advantages that: the adjusting frame is provided with a very reliable face contact locking mechanism which can avoid excursion of the adjusting frame caused by external influences, such as vibration; moreover, as the adjusting frame is integral, the production cost can be reduced by about 30 percent, and the difficulty in assembling the adjusting frame is reduced.

Description

technical field [0001] The invention relates to an integral two-dimensional optical adjustment frame. Background technique [0002] Optical adjustment mounts are mainly used to fix and adjust optical components in optical experiments or optoelectronic instruments, and are an indispensable part of optical precision machinery. Optical adjustment mounts are divided into one-dimensional adjustment mounts and two-dimensional adjustment mounts. One-dimensional adjustment mounts have only one adjustment screw, which can only adjust the lens angle in one direction; two-dimensional adjustment mounts have two or three adjustment screws, which can adjust the lens angle in two directions. Adjust the angle of the lens. [0003] Traditional optical adjustment mount structure such as Figure 1a , Figure 1b As shown, its structure is mainly composed of two structural parts, a fixed block 1' and an adjusting block 2', and several fine-toothed adjusting screws 3', wherein the fixed block 1...

AI Technical Summary

Problems solved by technology

[0004] The traditional optical adjustment mount has been used for many years, but due to its structural limitations, there are also some shortcomings, which cannot meet the increasing performance needs of modern optical machinery: 1. Its adjustment function is realized by two main structural fixing blocks and adjustment block parts, which is inevitable There are machining errors and matching errors, which affect the adjustment accuracy

2. The fixed block and the adjustment block are separated, and the adjustment screw and the fixed block are in point contact, which is prone to deviation due to external vibrations

3. Two complex structural parts need to be processed, the processing cost is high, and the technical requirements for assemblers are high
