Description
ERUTM128-25 1280×1024 Uncooled Infrared Thermal Core Module — 25 mm Lens
The ERUTM128-25 is a 1280×1024 uncooled infrared thermal core module built around a 12 µm vanadium oxide (VOx) detector, paired here with a 25 mm athermal objective. That combination produces a 34.2° × 27.6° field of view and a calculated detection range of approximately 2350 m against a human-size target — the widest field of view at 1280 × 1024 — large-area coverage with high pixel count.
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 25 mm lens
Because the detector carries 1.31 megapixels, the 25 mm lens still resolves fine detail across a 34.9° field of view. This is the configuration for projects that must see a lot of ground without losing the ability to identify what they see.
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.

Designed for OEM Integration
The ERUTM128-25 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 38 × 39 × 28 mm (fixed focal 14/19/25/35 mm); 68 × 69 × 24.7 mm (50 mm and motorised / continuous zoom) 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 25 mm lens the ERUTM128-25 is most often specified for:
- Wide-area UAV surveillance where one payload must cover a large footprint
- Airport, port and campus perimeter monitoring with high target detail
- Industrial inspection lines that need both coverage and resolution
- Robotic and autonomous platform perception
- Multi-sensor gimbals that pair thermal with daylight and ranging channels

Frequently Asked Questions
What is the field of view of the ERUTM128-25?
The 25 mm lens delivers a 34.9° × 28.2° field of view — the widest available in the ERUTM128 series. The field of view is set by the 25 mm athermal objective; other focal lengths in the ERUTM128 series are available if your project needs a wider or narrower scene.
How far can the ERUTM128-25 detect a person?
With a standard human target of 1.7 m × 0.5 m and a 2 K temperature difference, the calculated detection range is approximately 2350 m, with recognition at approximately 1200 m. Real-world range varies with target size, thermal contrast, atmospheric transmission and the display or software used for evaluation. Our engineers will run the DRI calculation for your specific target and lens choice on request.
Why choose the 25 mm lens?
Because the detector carries 1.31 megapixels, the 25 mm lens still resolves fine detail across a 34.9° field of view. This is the configuration for projects that must see a lot of ground without losing the ability to identify what they see.
What is the thermal sensitivity of the ERUTM128-25?
NETD is ≤30mK @ F#1.0 / 25℃, measured at 25 °C with an F#1.0 aperture. Lower NETD means smaller temperature differences become visible, which matters when contrast is low — for example at long range or in humid air.
What interfaces does the ERUTM128-25 support?
Digital video: DVP16 / BT1120 / USB3.0 / MIPI-DSI-4LANE (expansion: USB3.0 / SDI / HDMI / GIGE / CameraLink / VPC / MIPI-CSI-2LANE). Communication: TTL-232 / USB3.0. Supply: 2.7V – 5.3V. The interface board can be exchanged at the factory to match your processing platform, and the ERUTM128 series supports Windows and Linux SDK integration over USB 3.0.
Does the ERUTM128-25 support OEM / ODM customisation?
Yes. As a manufacturer we can adapt the lens, interface board, housing, mounting, firmware features and packaging to your project. Custom configurations are quoted individually — send us your target distance, platform, interface and volume and we will propose a configuration.
Request a Quotation
We do not publish fixed prices because every project differs in lens, interface, housing and volume. Send us your target distance, platform type, interface requirement and estimated annual quantity, and our engineers will return a configuration proposal and quotation for the ERUTM128-25.
