With the rapid development of science and technology, the technology of uncooled detector is becoming more and more mature, long wave infrared uncooled optical system has been widely used in military and civil fields. Since infrared optical materials and mechanical materials will produce thermal changes when the temperature changes, the change of working environment will cause the focal length change of the optical system, the image surface is elegant, and the imaging quality is reduced. In order to eliminate or reduce the influence of temperature change on the optical system imaging, the corresponding compensation technology must be adopted, which is the electric focusing long-wave infrared lens and its working method, not only the structure is reasonable, but also efficient and convenient. The optical system is stable in a large temperature difference range to ensure good imaging quality. Compared with the prior art, the invention has the following advantages: the structure design of the invention is simple, compact, reasonable, the optical system is stable, and the imaging quality is good.

Due to the wide application of this technology, the market demand for electric focusing long infrared lens is gradually increasing, and machine vision plays a crucial role in precision production, through the connection between CCD and external communication, the precise positioning of products can be achieved, the alignment of components, component detection, component size measurement, two-dimensional code recognition, and other components. For many functions that cannot be achieved manually, CCD replaces traditional low-speed and rough manual operations to achieve high-speed, accurate and efficient operations, which not only improves the efficiency of production, but also reduces the cost of input labor.

The front lens A is arranged in the front lens barrel and pressed by the front pressure ring, and the rear lens B is arranged in the back lens barrel and pressed by the back pressure ring. A rotating sleeve is arranged on the outer side of the back end of the front set of mirror barrel, and the rear set of mirror barrel is arranged through the inner side of the back end of the front set of mirror barrel, and the rotating sleeve, the front set of mirror barrel and the back set of mirror barrel are connected together through the CAM guide nail. The rotating sleeve is provided with a curve groove for matching with the CAM guide nail, and the front set of mirror barrel is provided with a straight groove for matching with the CAM guide top, and one end of the CAM guide nail is fixed with the back set of mirror barrel. The other end of the CAM guide pin extends into the curved groove through the straight groove.
