The ERUTM64-50 is a 640×512 uncooled infrared thermal core module built around a 12 µm vanadium oxide (VOx) detector, paired here with a 50 mm athermal objective. That combination produces a 8.8° × 7.0° field of view and a calculated detection range of approximately 4700 m against a human-size target — the longest focal length in the 640 series — maximum reach from the smallest core.

Like the rest of the ERUTM64 (640 × 512) family, the core delivers NETD of ≤35 mK, 50Hz real-time output and <0.85 W power consumption, so it can be embedded in battery-powered and space-constrained platforms without a dedicated thermal design.

Why the 50 mm lens

The 50 mm lens gives the 640 series its greatest reach while keeping the same compact core, low power draw and 50 Hz output as the rest of the family. It suits installations where a single camera must cover a very large area.

Field of view, detection distance and pixel density on target are all governed by the focal length. The table below shows how the ERUTM64 series behaves across its lens options, so you can match the module to the distance your project actually operates at.

Key Features

• 640×512 high-resolution uncooled VOx infrared detector with 12 µm pixel pitch
• 50 mm athermal objective giving a 8.8° × 7.0° field of view
• NETD ≤35mK@25℃,F#1.0 for detecting small temperature differences
• 50Hz real-time thermal video output
• <0.85 W typical power consumption at 25 °C
• Long-wave infrared spectral response of 8–14 µm
• BT656 / CameraLink / MIPI / USB / SDI (via replaceable interface board)
• UART × 2 / RS232 × 2
• 4× digital zoom and multiple colour palettes (white hot, black hot, iron red, red hot)
• Built-in image processing: non-uniformity correction, time-domain and spatial filtering, digital detail enhancement
• Industrial operating range of −40 °C to +60 °C

Designed for OEM Integration

The ERUTM64-50 is supplied as a bare core so that system integrators can mount it directly against their own optics, housing and processing board. With dimensions of 26mm × 26mm × 25mm and the interface set listed above, it fits platforms where a complete camera would be too large.

Integration support covers interface-board selection, communication protocol documentation, lens alternatives, mounting geometry and firmware parameter tuning. Where a project needs a different field of view, the same core is available with other focal lengths in the ERUTM64 series.

Typical Applications

With a 50 mm lens the ERUTM64-50 is most often specified for:

• Maritime and coastal surveillance from shore stations and vessels
• Long-range border security along open and mountainous terrain
• High-mast and tower-mounted thermal cameras
• Long-range UAV observation for reconnaissance missions
• Counter-UAS and wide-area detection projects
