Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, and particularly relates to a lens connecting device for a laser emitting device. Background Art

[0002] A laser emitting device is a device used to generate, amplify, and emit laser beams. As the scope of use of laser emitting devices by users expands, the demand of specific users for expanding the capabilities of laser emitting devices is also constantly expanding, giving rise to many new demands. For example, when the fire department rescues trapped people in high-rise residential buildings, it needs to enter from outside the building; when the gardening department clears the high branches of trees that affect the safe operation of roadside high-voltage lines, etc. In such scenarios, if a circular light spot is used, the working efficiency is low and the requirement for pan-tilt control is high. Therefore, a long-strip light spot is needed; when using a laser to destroy unexploded ordnance, a circular light spot can effectively dispose of various dangerous and explosive substances because it forms a high-energy density light spot by focusing and heats and ablates the metal shell. Therefore, a circular light spot is needed.

[0003] In summary, the same laser emitting device may need to use different beam shaping devices in different application scenarios to provide different light spot shapes, and be installed or disassembled according to different application scenarios to meet different task requirements and improve the working efficiency in different scenarios. Therefore, there is an urgent need for a lens connecting device that is both convenient to disassemble and convenient to install and fasten, so as to quickly switch lenses in different application scenarios.

[0004] The fine-tuning tilt angle of an optical lens needs to reach very high precision. Since the imaging quality of an optical system is very sensitive to the position and angle of the lens, even a small angle deviation may cause a significant decrease in the imaging quality. Therefore, during the fine-tuning process, high-precision measurement and adjustment equipment, such as an optical collimator, an autocollimator, etc., are needed to ensure that the adjusted angle is accurate. However, due to structural or volume reasons, the above-mentioned instruments are difficult to be integrated into the imaging system. Therefore, there is an urgent need for a lens connecting device for a laser emitting device that is convenient to adjust and small in volume to quickly switch beam shaping lenses in different scenarios.
