The ERUTM128-50 is a 1280×1024 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 17.5° × 14.0° field of view and a calculated detection range of approximately 4700 m against a human-size target — high-detail imaging at medium-long range.

Like the rest of the ERUTM128 (1280 × 1024) family, the core delivers NETD of ≤30 mK, 25Hz / 30Hz / 50Hz real-time output and ≤1.2 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 athermal lens brings the field of view down to 17.9° while the 1280 × 1024 detector continues to resolve fine thermal detail, making this the configuration for identifying rather than merely detecting targets.

Field of view, detection distance and pixel density on target are all governed by the focal length. The table below shows how the ERUTM128 series behaves across its lens options, so you can match the module to the distance your project actually operates at.

Key Features

• 1280×1024 high-resolution uncooled VOx infrared detector with 12 µm pixel pitch
• 50 mm athermal objective giving a 17.5° × 14.0° field of view
• NETD ≤30mK @ F#1.0 / 25℃ for detecting small temperature differences
• 25Hz / 30Hz / 50Hz real-time thermal video output
• ≤1.2 W typical power consumption at 25 °C
• Long-wave infrared spectral response of 8–14 µm
• DVP16 / BT1120 / USB3.0 / MIPI-DSI-4LANE (expansion: USB3.0 / SDI / HDMI / GIGE / CameraLink / VPC / MIPI-CSI-2LANE)
• TTL-232 / USB3.0
• 8× 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 ERUTM128-50 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 68 × 69 × 24.7 mm (50 mm and motorised / continuous zoom); 38 × 39 × 28 mm (fixed focal 14/19/25/35 mm) 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 ERUTM128 series.

Typical Applications

With a 50 mm lens the ERUTM128-50 is most often specified for:

• Long-range surveillance where target identification matters
• Maritime observation from vessels and shore stations
• Border security across open terrain
• High-detail UAV imaging for infrastructure inspection
• Scientific and industrial thermography at distance
