640 × 512 thermal imaging in a module for drones and embedded systems
Thermal imaging cameras IR-SF641 Mini infrared module for OEM integration
IR-SF641
A thermal core ready to build into inspection, monitoring and airborne systems.
A complete thermal core
The IR-SF641 packs an uncooled VOx detector of 640 × 512 with 12 µm pixel pitch and a thermal sensitivity of ≤ 30 mK at 50 Hz, over the 8-14 µm band — the imaging heart of an inspection or surveillance system, ready to integrate.
Optics for every distance
Six athermalised fixed lenses (9 to 75 mm; 9-25 mm for the IR-SF641R variant) keep focus regardless of ambient temperature, and DDE detail enhancement, polarity switch and 1-8× digital zoom condition the image before output.
Main features
- Analogue PAL or NTSC video output on one channel.
- UART control (TTL 3.3 V) with reserved user I/O.
- Automatic calibration at power-on, plus manual calibration.
- Automatic or manual brightness and gain.
- Single 5 V DC supply, suited to low-power platforms.
Applications and variants
Applications
- Drones and airborne platforms.
- Industrial temperature measurement systems.
- Security control and outdoor sighting.
- Applications with tight volume and power budgets.
Two variants
The IR-SF641 offers the full lens set from 9 to 75 mm, while the IR-SF641R keeps the compact set of 9, 13 and 25 mm; both share the same detector, processing and interfaces.
