R&D Scene
Thermal imaging cameras can indicate material properties under the most demanding conditions and Perform non-contact temperature measurement. a series of infrared sensors Type and optical properties make infrared thermal imaging a number of research environments An indispensable part.

Infrared thermal imaging cameras can clearly image small objects, which is of great help to the effect of microscopic imaging. Some similar objects under visible light will show differences in infrared thermal imaging cameras.

Thermal imaging lens can detect extremely small temperature difference, convert the temperature difference into real-time video image display, can see through obstacles such as fog, rain, smoke, etc. It can be used in extreme weather, can be used normally during the day and night, and all hot objects are nowhere to hide


Scientists designing and manufacturing circuit boards face the task of managing heat dissipation How to balance the performance or cost of the problem. Accurate understanding of thermal issues Straight is a very difficult thing. However, with thermal imaging, Engineers can easily observe the equipment they manufacture Thermal mode and quantitative analysis to design better products

Medical Field
Infrared thermal imaging technology is outstanding in the medical field, using the infrared radiation energy of the human body itself, and through the photoelectric signal conversion, the infrared radiation information of the human body surface is finally presented in the form of a pseudo-infrared thermal image. This can help the experts to conduct a more comprehensive diagnosis, and some areas of the disease caused by inflammation, combined with high-precision detectors, can find more subtle symptoms.

Gun Sight
Thermal imaging guns can clearly see people, weapons and animals in harsh environments such as full black, smoke, dust, rain and snow, trees, camouflage, etc. This has a great effect on finding enemy conditions in advance and quickly finding prey, which can meet fast high-precision stable shooting. Light weight, small size, easy to carry

Tips for How to Clean IR Lens

Cleaning IR Lens & infrared lens Methods:Blow the infrared lens with clean air to remove dust that floats on the IR lens surface;Dust with specific lens brush; Apply solvent directly to the pad, and slow, even, light pressure working from edge to edge across the optic allowing solvent to evaporate directly behind pad.
