Description
ERUTM64-19 640×512 Uncooled Infrared Thermal Core Module — 19 mm Lens
The ERUTM64-19 is a 640×512 uncooled infrared thermal core module built around a 12 µm vanadium oxide (VOx) detector, paired here with a 19 mm athermal objective. That combination produces a 22.9° × 18.4° field of view and a calculated detection range of approximately 1800 m against a human-size target — the balanced workhorse of the 640 series — roughly twice the reach of the 9 mm while keeping a usable field of view.
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 19 mm lens
The 19 mm configuration is the most widely specified lens in the series because it keeps a wide enough field of view for situational awareness while roughly doubling the detection distance of the 9 mm version.
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.

Designed for OEM Integration
The ERUTM64-19 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 19 mm lens the ERUTM64-19 is most often specified for:
- UAV gimbal payloads for day/night aerial imaging and inspection
- Fixed security and perimeter cameras covering a yard, gate or fence line
- Handheld and tripod-mounted observation devices
- Search and rescue optics used from helicopters and drones
- Vehicle and marine night-vision systems

Frequently Asked Questions
What is the field of view of the ERUTM64-19?
The 19 mm athermal lens delivers a 23.9° × 19.2° field of view, giving roughly twice the detection range of the 9 mm configuration. The field of view is set by the 19 mm athermal objective; other focal lengths in the ERUTM64 series are available if your project needs a wider or narrower scene.
How far can the ERUTM64-19 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 1800 m, with recognition at approximately 900 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 19 mm lens?
The 19 mm configuration is the most widely specified lens in the series because it keeps a wide enough field of view for situational awareness while roughly doubling the detection distance of the 9 mm version.
What is the thermal sensitivity of the ERUTM64-19?
NETD is ≤35mK@25℃,F#1.0, 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 ERUTM64-19 support?
Digital video: BT656 / CameraLink / MIPI / USB / SDI (via replaceable interface board). Communication: UART × 2 / RS232 × 2. Supply: 5V ± 0.5. The interface board can be exchanged at the factory to match your processing platform, and the ERUTM64 series supports UART and RS232 control.
Does the ERUTM64-19 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 ERUTM64-19.
