Long-wave IR (LWIR): 8–14 μm
METRA-256-15UT combines a 256×192/12μm VOx uncooled LWIR core with a 15.4 mm F1.0 lens, dual-range radiometry (-20~150℃ / 100~550℃, ±2℃/±2%) and UVC plug-and-play USB 2.0 in a 32.09 × 20 × 20 mm body weighing ≤22 g.
The Metra series packs a complete radiometric LWIR imaging chain into a 20×20mm cross-section core built for integration into robots, security housings and pods. The METRA-256-15UT pairs a 256×192/12μm VOx uncooled detector (≤50 mK NETD) with a 15.4 mm F1.0 lens (11.4°×8.6° FOV) and streams standard UVC video over USB 2.0 at 50 Hz. Dual-range radiometry covers -20~150℃ and 100~550℃ at ±2℃/±2% accuracy with full-screen per-pixel temperature output; measuring distance reaches 25 m for a 0.1×0.1m target. At ≤22 g and ≤0.5 W, it drops straight into size- and power-constrained devices.
