content: I believe this is a new product that seems to good to be true? From unknown company "BSIDE"?240x240 thermal resolution in a handheld device with capacitive screen for 140€ would be really handy if sensor is decent...Specifications:- Sensor Type: Vanadium oxide (VOx) microbolometer- Response Band: 8 ~ 14 microns- Thermal Image Resolution: 240x240 pixels- Noise Equivalent Temperature Difference: ≤60 mK(@25°C,F#1.0)- Angle of View (FOV): 50.0° (H) x 50° (V) / 72.1° (D)- Spatial Resolution: 8.89 mrad- Frame Frequency: 25Hz- Imaging Lens Focal Length: 1.35 mm- Temperature Measurement Focal Length: Adjustable from 0.3m to 3m- Temperature Range: -20°C~550°CSH7 Thermal MultimeterEDIT:Sorry for aff links. Have removed it after. Won't do that mistake again...

content: The claimed thermal resolution is the clue to the low cost. This is yet another unit that is using the 96x96 pixel microbolometer that has its output enhanced to 240x240 pixels using “SuperIR” image enhancement. HikMicro use the same thermal core in their “Eco” range but they are honest about the true optical resolution of the microbolometer and the fact that the displayed 240x240 pixel image is the result of software based image enhancement. I suspect it is using the old super resolution technique that uses hand shake and multiple image capture to effectively increase the displayed resolutionBe suspicious of any thermal camera that states 240x240 pixel resolution. The unusual “square” aspect ratio resolution figures can also be a clue to the use of this economy imaging core.https://www.tester.co.uk/hikmicro-eco-eco-v-handheld-thermal-camera?gad_source=1&gbraid=0AAAAADvjJv36CdOJcYqAx9PQCZxn--za-&gclid=Cj0KCQiAz6q-BhCfARIsAOezPxmlKj_uxcGCryYTs_1oSidVBSck2UTQpK1XxwmiTeebpwfekJth34gaAg9nEALw_wcB#589=26994Fraser

content: I was wrong. SuperIR is an AI based image enhancement algorithm rather than the old super resolution technique.https://www.hikmicrotech.com/pt/explore/industrial-blog/HIKMICRO-SuperIR-An-Advanced-Algorithm/Fraser

content: I have done quite a bit of digging and cannot find any reference or datasheet for the new 96x96 pixel microbolometer core that is becoming more common in the marketplace. At the moment I am left thinking these “Economy” thermal imaging devices that claim 240x240 pixel resolution are using a HikMicro sourced 96x96 pixel imaging core with its associated SuperIR AI algorithm.I have no issue with a company offering a 96x96 pixel resolution thermal camera (such is useable for non demanding tasks). However, any that claim 240x240 pixel thermal resolution without making it clear that SuperIR enhancement is used on a base 96x96 pixel microbolometer are trying to mislead potential buyers.The old saying….”If it looks too good to be true, it probably is” applies to the price of retail thermal imaging cameras.Fraser

content: If I recall the latest revisions of Flir Leptons 3.1R are native 240x240 and likely that core, they are trying to bamboozle people into thinking it is.while it clearly ain't at those prices..This is likely one of the lower tier Chinese Hikmicro cores upscalled to claim those 240x240 merits... likely 96x96 sensor in native res' as Fraser indicated.

content: DaneLaw,A 240x240 pixel FLIR Lepton core ?I missed that news and I must say that I am pleasantly surprised. I thought Lepton had reached its limit at 160x120 pixels and Boson was for all applications requiring higher resolution. I was hoping that FLIR would continue to develop the Lepton core to bring it up to date with the current marketplace. Is this a new version of the Lepton 3.1R as the datasheets I have in my archive say it is a 160x120 pixel core ?Fraser

content: Quote from: Fraser on March 07, 2025, 05:13:32 pmYeah, I missed that memo too.. its not correct, my bad.. no 240x240 cores in the Lepton series..
