Not long ago, a thermal imager with a refresh rate of 25 Hz, manual focus adjustment, acceptable matrix resolution, and even in a compact case - was considered something unimaginably fantastic. Now it has become a common reality - this year Infiray released several models of mobile thermal imagers, which already implement these convenient features. We will consider one of these models today in this review, and at the same time see examples where this tool can be useful. Main characteristics Matrix resolution — 256x192 Frame rate — 25 fps Focus — adjustable Viewing angle — 19.6° (horizontal) 14.7° (vertical) The lens is made of expensive metal germanium — this material does not transmit the visible spectrum, unlike cheaper zinc selenide. Focal length of 9 mm — this means a narrow field of view and increased visibility of distant objects (for example, a person can be identified at 150 meters, a wild boar at 200 meters, and human movement can be detected at 870 meters). The diameter of the lens is about 10 mm. The focus adjustment ring with knurling has a pleasant smooth movement, rotation occurs along the thread. Installed microbolometric matrix of Infiray's own production, its resolution is 256x192. The size of a single pixel of the matrix is ​​12 microns, which the manufacturer writes down as an advantage over matrices with a pixel size of 17 microns. The package is Spartan. This is a USB-C extension cable from "F" to "M" and a small hard case with a zipper with a foam insert. Previously, the seller equipped the thermal imager only with a cable and a case. Conclusions The Infiray T2 Search is a very interesting model with a smooth 25 Hz picture and focus adjustment, allowing you to "squeeze" sharpness out of each pixel. It has a competent ratio of the long focal length of the lens and the small resolution of the matrix, which is why at long distances it can easily compete with almost twice as expensive models. Although the original purpose of the T2 Search model is search activities in natural conditions, it will be an indispensable thing when hunting for beaver, as well as when hunting other types of animals, such as roe deer, wild boar and large-hoofed animals - elk and deer! (which is hinted at by its name - Search), the tool also copes quite well with ordinary engineering and household tasks, such as finding heating fragments of equipment, repairing electronics, detecting thermal circuits and searching for thermal leaks.
