Compact Radiometric LWIR

METRA-640-19UT — Compact 640×512 Radiometric LWIR Module

Long-wave IR (LWIR): 8–14 μm

METRA-640-19UT combines a 640×512/12μm VOx uncooled LWIR core with a 19 mm F1.0 lens, dual-range radiometry (-20~150℃ / 100~550℃, ±2℃/±2%) and UVC plug-and-play USB 2.0 in a 37.04 × 20 × 20 mm body weighing ≤32 g.

Overview

The Metra series packs a complete radiometric LWIR imaging chain into a 20×20mm cross-section core built for UAV pods, helmets and smart-equipment integration. The METRA-640-19UT pairs a 640×512/12μm VOx uncooled detector (≤40 mK NETD) with a 19 mm F1.0 lens (22.8°×18.4° FOV) and streams standard UVC video over USB 2.0 at 30 Hz. Dual-range radiometry covers -20~150℃ and 100~550℃ at ±2℃/±2% accuracy with full-screen per-pixel temperature output; measuring distance reaches 30 m for a 0.1×0.1m target. At ≤32 g and ≤0.7 W, it drops straight into size- and power-constrained devices.

Key Features

Full-Field Radiometry

  • Dual measuring ranges: -20℃~150℃ and 100℃~550℃, ±2℃ or ±2% of reading (whichever is greater)
  • Full-screen per-pixel temperature data output for analytics and alarms
  • 10 areas + 10 points + 1 line

UVC Plug-and-Play over USB 2.0

  • Standard UVC protocol — no driver development on the host side
  • USB 2.0 via 25-pin FPC or 30-pin board-to-board connector (functionally identical)

Compact, Low-Power Integration

  • 37.04 × 20 × 20 mm body at ≤32 g, ≤0.7 W from a 5 V rail
  • -40℃ ~ +70℃ operating range; M1.6 mounting points on the body

Detector Anti-Burn Protection

  • Built-in protection shields the microbolometer from intense IR sources such as the sun
