[0001] The utility model relates to the technical field of infrared thermal imagers, in particular to an infrared thermal imager based on a laser rangefinder embedded in a lens. Background Art

[0002] In the process of using infrared thermal imager sights, a laser rangefinder is usually added to identify the distance to the target for accurate shooting. At present, most infrared thermal imagers use external laser rangefinders, and a few use built-in ones. The external rangefinder is an independent rangefinder that is hung and fixed on the outside of the thermal imager casing.

[0003] The use of laser rangefinders requires accuracy, convenience and appearance coordination. External laser rangefinders are generally bulky and require independent buttons to operate. The disadvantage of built-in laser rangefinders is that optical axis debugging cannot be conveniently performed, resulting in poor use of the laser rangefinder. Utility Model Content

[0011] Preferably, a wiring head is provided at one end of the infrared detection sensing module close to the circuit processing module, the infrared detection sensing module is connected to the circuit processing module via a signal line, and one end of the optical system module is detachably connected to the mounting frame via a groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model installs the laser rangefinder body in the entire optical system module through an adapter bracket during optical assembly, then installs the optical system module containing the laser rangefinder inside the housing, and installs the infrared detection sensing module and the circuit processing module inside the housing through structural parts. At the same time, the transmission cable of the laser rangefinder body is connected to the circuit processing module, so that the circuit processing module can receive the target distance information detected by the laser rangefinder body, which can reduce the inconvenience of optical axis debugging caused by the built-in rangefinder, and because the assembly method does not occupy the external space of the housing, the overall appearance of the sight is not affected, so the appearance and size can be well guaranteed, so that the overall design effect of the infrared thermal imager is better;

[0017] 2. In traditional designs, optical axis debugging may involve complex cable connections, which not only increases the complexity of assembly, but may also introduce interference and loss in signal transmission. In contrast, this structure adopts an integrated design, where the laser rangefinder is integrated with the lens, omitting complex cable connections and using a simpler assembly process to ensure accurate alignment and calibration of the optical system. By optimizing the assembly process and the accuracy of components, the error in the assembly process can be effectively reduced, thereby simplifying the debugging process and improving assembly efficiency.

[0018] 3. Optical axis alignment is a crucial step in infrared thermal imagers, which directly affects the imaging quality and performance stability. The optical axis of the laser ranging and the infrared optical axis inside the entire lens of this imager are close. Through design tolerance control and precision machining technology, the optical axes of the laser ranging and infrared thermal imaging are ensured to remain close or parallel during the assembly process, minimizing possible deviations in the optical system. This structure can improve the ranging accuracy of the equipment, thereby better meeting the user's needs for precise imaging and achieving reliable performance in various environments.
