Double-beam parallelization and collimation regulating device

Abstract

The invention provides a double-beam parallelization and collimation regulating device. A light source A of the double-beam parallelization and collimation regulating device can only slightly move up and down and incline under the control of a spring and a screw; a light source B of the double-beam parallelization and collimation regulating device can only slightly move left and right and incline under the control of a spring and a screw; light rays emitted by the light source A and the light source B are mutually parallel through regulation of the screws and the springs; a protective sleeve is mounted with a horizontal rotating shaft; the protective sleeve can change the pitching angle around the rotating shaft under the control of the screws and the springs; one side of a shaft hole in the protective sleeve is circular, and the other side is elongated in the light-emitting direction of the light sources, so that the protective sleeve can horizontally rotate left and right at a small angle under the control of the screws and the springs; the pitching angle and the horizontal angle of the protective sleeve change an included angle between parallel light. The double-beam parallelization and collimation regulating device has the benefits as follows: the double-beam parallelization and collimation regulating device can regulate the included angle between the light emitted by the two light sources to obtain the parallel light, and can synchronously regulate the directions of the two light beams as a whole so as to being irradiated to a predetermined target; the double-beam parallelization and collimation regulating device is simple in structure and flexible to operate, and can be widely applied to a double-beam or multi-beam optical instrument.

Description

technical field [0001] The invention relates to an optical path adjustment device, in particular to a double beam parallel and collimation adjustment device. Background technique [0002] Parallel double beams are sometimes used in teaching, scientific research or industrial production. At present, there are laser pointers with two-color laser output on the market, but the positions of its two light sources are relatively fixed, and the angle between them is generally not zero degrees, that is, they are not strictly parallel and cannot be adjusted. The inventor previously applied for a utility model patent for the technology of separately adjusting two light sources with screws to achieve parallel light: Handheld Dynamic Light Wave Diffraction Demonstration Instrument, application number CN201320481617, publication number CN203366619U. After reaching parallel, it is impossible to change the direction of the two beams of light synchronously, that is, the direction of each li...

Problems solved by technology

The inventor previously applied for a utility model patent for the technology of separately adjusting two light sources with screws to achieve parallel light: Handheld Dynamic Light Wave Diffraction Demonstration Instrument, application number CN201320481617, publication number CN203366619U. After reaching parallel, it is impossible to change the direction of the two beams of light synchronously, that is, the direction of each light source must be adjusted independently at any time, and no spring is used, and the number of screws used is too many, reaching 12. The technical requirements are very high, the adjustment range is also very limited, and failures are prone to occur during use.
