DALI-IRtech    MODULE    UNCOOLED THERMAL MODULE    SF641 Mini-Infrared Module

SF641 Mini-Infrared Module

◆ 640×512, 384×288 pixel uncooled vanadium oxide (VOx) detector
◆ Premium imaging: Professional algorithms (NUC, noise reduction, DDE) deliver refined visuals with clear gradation
◆ Accurate thermometry: High-precision measurement (±2℃ or ±2% of reading)
◆ Compact & portable: Miniaturized design (26mm×26mm), lightweight (22g without lens), ultra-low power consumption (<1W)
◆ Versatile interfaces: LVCMOS (BT656 support), USB Type-C (via expansion module), SDI (via expansion module)
