The IR-SF641 packs an uncooled VOx detector of 640 × 512 with ≤ 30 mK sensitivity into a module for drones, industrial temperature measurement and embedded systems, running from a single 5 V DC supply.
Advantages
A thermal core, not a camera
Designed for integration: analogue PAL/NTSC video output, UART control (TTL 3.3 V), reserved user I/O and 5 V DC supply for platforms with tight volume and power budgets.
Detail where it matters
The 12 µm pixel-pitch detector delivers ≤ 30 mK sensitivity at 50 Hz over the 8-14 µm band, with DDE digital detail enhancement and noise reduction.
Optics that ignore temperature
Athermalised fixed lenses from 9 to 75 mm hold focus in high- and low-temperature environments; the IR-SF641R variant offers the compact 9-25 mm set.
Self-managed image
Automatic calibration at power-on, manual calibration on demand, polarity switch, 1-8× digital zoom and automatic or manual brightness and gain.
Applications
- Drones and airborne platforms.
- Industrial temperature measurement systems.
- Security control and outdoor sighting.
- High-volume applications with strict power requirements.
About the product
The IR-SF641 and IR-SF641R share detector, processing and interfaces; they differ in the available lens sets. As an integration module, the electrical interface concentrates power, analogue video and user I/O on a 16-bit connector.

Frequently asked questions
What is the difference between the IR-SF641 and the 641R?
The lens set: 9 to 75 mm in the IR-SF641 and the compact 9, 13 and 25 mm set in the IR-SF641R; detector and interfaces are shared.
How does it integrate into a system?
Via one PAL or NTSC analogue video channel and a UART control line at TTL 3.3 V, with reserved user I/O and a single 5 V DC supply.
Does it need refocusing with temperature changes?
No. The athermalised fixed lenses keep focus in high- and low-temperature environments.
How is the image calibrated?
Automatically at power-on and manually on demand, with automatic or manual brightness and gain control.
Is it a complete camera?
No. It is an OEM thermal core: it provides the detector, the processing and the interfaces, and the integrator adds the housing, the power supply and the application electronics. That is why it fits drones, embedded systems and industrial equipment with very tight volume and power budgets.
