Mini infrared module for OEM integration, 640 × 512
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.
