Uncooled 640×512 12μm LWIR Thermal Camera Module

Overview

The Uncooled 640×512 12μm LWIR Thermal Camera Module is a compact, low-power thermal imaging core designed for OEM integration into UAVs, drones, security systems, industrial inspection equipment, and embedded vision devices.

Built around an uncooled vanadium oxide (VOx) focal plane array detector, this thermal camera module captures long-wave infrared radiation in the 8–14μm spectral range. Its high-resolution 640×512 imaging option, 12μm pixel pitch, and NETD of ≤40mK at F1.0 enable detailed thermal imaging, including scenes with subtle temperature differences.

With a compact form factor, lightweight construction, CVBS analog video output, USB 2.0 connectivity, and flexible image-processing functions, the module is designed for integration into space-constrained imaging systems.
