Description

Technical Field

[0001] The utility model belongs to the technical field of infrared thermometers, in particular to a video aiming infrared thermometer. Background Art

[0002] Infrared thermometers are based on the blackbody radiation law, that is, any object will emit thermal radiation at any temperature. Thermal radiation exists in the form of infrared rays that are invisible to the human eye. This radiation energy is proportional to the temperature of the object, that is, the higher the temperature, the greater the radiation energy. Infrared thermometers receive infrared radiation emitted from the surface of an object, convert it into an electrical signal, and then process it through an internal circuit to finally display the temperature value of the surface of the object. Non-contact infrared thermometers have developed rapidly in technology, with continuous improvement in performance, continuous expansion of application scope, and increasing market share year by year. In order to adapt to different application requirements, related technologies have emerged with infrared thermometers with integrated eyepiece aiming functions, such as existing patent applications 201120242390.5, 202111552091.6, 201010164390.8, etc., all of which disclose infrared temperature measuring devices with integrated eyepiece aiming functions.

[0008] And a video aiming module, the video aiming module includes a beam splitter and a digital camera, the reflector, the beam splitter and the eyepiece aiming lens group are optically coaxially arranged, the digital camera is arranged opposite to the beam splitter, the light transmitted through the beam splitter reaches the eyepiece aiming lens group, and the light reflected by the beam splitter reaches the digital camera.

[0009] Furthermore, the front flat mirror and the focusing lens are arranged to be synchronously adjustable, and the synchronous adjustment is synchronous movement forward and backward, which is convenient for adjustment and ensures the reliability, stability and precision of the focusing lens adjustment.

[0010] Preferably, the digital camera can be replaced by an LED light emitter and a laser transmitter.

[0011] Beneficial effect: With the video aiming infrared thermometer of the utility model, the operator aims at the target temperature measuring point by observing the imaging of the digital camera, which replaces the existing operator aiming at the target temperature measuring point through the eyepiece, thereby overcoming the defect of the existing "when aiming at the target temperature measuring point through the eyepiece, the aiming effect is inconsistent and poor due to the observation and vision differences of the operator, and the best objective lens focusing measurement effect cannot be achieved".
