Precision mirror frame based on a flexible hinge

Abstract

The present invention relates to a precision mirror frame based on a flexible hinge, and belongs to the technical field of optical components. The mirror frame includes a mirror group for mounting a mirror, a base for supporting the mirror group, and an adjusting unit for adjusting the angle of the mirror group. The base includes a fixing plate and a connecting plate disposed between the fixing plate and the mirror group, and the fixing plate and the connecting plate are hinged by the first hinge. The connecting plate and the mirror group are hinged by a second hinge, and the first hinge and the second hinge define a different rotation direction. The fixing plate is provided with an adjusting unit, and the adjusting unit is an adjusting bolt. The mirror set includes an adjustment plate, amirror holder, and a mirror press ring. The mirror frame has the advantages of simple structure, convenient installation, and the functions of the mirror adjusting unit and the fixed frame of the existing fine screw with the spring, which ensures the precision and stability of the mirror adjustment, and reduces the adjustment difficulty of the mirror frame, with wide application space.

Description

technical field [0001] The invention belongs to the technical field of optical components, in particular to a flexible hinge-based precision mirror frame. Background technique [0002] Mirror holders are mainly used to change the propagation direction of light beams, and are widely used in optical-related scientific experiments, instruments and engineering projects. The reflector frame used in scientific experiments usually uses fine-tooth screws and springs to adjust the angle of the reflector surface. The adjustment accuracy is high and repeated adjustments can be realized, but the stability is poor. The adjusted optical path is easily affected by vibration. Influenced by external factors such as temperature, it is not suitable for use in high-vibration platforms such as vehicles. In optical equipment or engineering tasks, fixed mirror frames are usually used. After the optical path is adjusted, screw fastening or glue curing is used to fix it to prevent external vibratio...

Problems solved by technology

The reflector frame used in scientific experiments usually uses fine-tooth screws and springs to adjust the angle of the reflector surface. The adjustment accuracy is high and repeated adjustments can be realized, but the stability is poor. The adjusted optical path is easily affected by vibration. Influenced by external factors such as temperature, it is not suitable for use in high-vibration platforms such as vehicles

In optical equipment or engineering tasks, fixed mirror frames are usually used. After the optical path is adjusted, screw fastening or glue curing is used to fix it to prevent external vibrations from affecting the optical path. However, the adjustment accuracy of this mirror frame is difficult to grasp. Optomechanical engineers have high technical requirements
