KB Series

KB Series Introduction to Parameters

KB Series uncooled infrared thermal imaging modules deliver high-performance thermal imaging in an ultra-compact, lightweight, and low-power package, fully meeting SWaP (Size, Weight, and Power/Price) requirements. Available in 384×288 and 640×512 resolutions with advanced 12 µm VOx detectors, these modules combine high sensitivity (NETD ≤40 mK), refined image processing algorithms, and excellent expandability.

They produce clear, detailed thermal imagery with continuous digital zoom (1–8×), multiple polarity/pseudo-color options, image mirroring, and shutter-based NUC. Flexible interfaces (CVBS/AHD analog plus BT.601/BT.656, USB 2.0, Camera Link, SDI digital) and UART control allow seamless integration into intelligent platforms. Typical power consumption is under 0.42 W (KB3) / 0.7 W (KB6) via USB, with a module size of just 21 × 21 × 26.2 mm and weight below 10–15 g (excluding lens).

Ideal for UAV EO/IR gimbals, security surveillance, outdoor thermal systems, night-vision equipment, industrial inspection, and custom secondary development. Wide operating temperature range (−40 °C to +80 °C), robust vibration/shock resistance, and optional lens driving (focus/zoom/auto-focus) make the KB Series a reliable, cost-effective core for next-generation thermal solutions.

Frequently Asked Questions about the KB Series Uncooled Thermal Imaging Modules

Is secondary development supported?

Yes. Multiple digital interfaces, UART communication, and rich expandable functions make the KB Series easy to integrate into customer systems for secondary development.

Is shutterless operation available?

Standard NUC is shutter-based. Shutterless algorithm is available on other KPT series (e.g., KR). Please contact us if shutterless is required for specific applications.

Does it support continuous digital zoom and image enhancement features?

Yes. Continuous digital zoom from 1.0× to 8.0× (0.1 step), brightness/contrast adjustment, multiple pseudo-color/polarity modes, image mirroring, PIP, crosshair, and hotspot tracking are all supported. Advanced image processing algorithms deliver clear and detailed thermal images.

Can the interfaces be customized?

Yes. The series supports a variety of digital interfaces (BT.601/BT.656, USB 2.0, Camera Link, SDI, etc.). Some interfaces can be customized according to customer requirements for flexible integration with different intelligent processing platforms.

What applications is the KB Series best suited for?

UAV EO/IR gimbals, security & surveillance systems, outdoor thermal cameras, night-vision devices, industrial inspection, handheld thermal imagers, and any SWaP-constrained secondary development projects.

What are the main differences between KB3 and KB6?

KB3 uses 384×288 resolution with lower power consumption (<0.42 W) and lighter weight (<10 g). KB6 offers higher 640×512 resolution for finer detail, with power <0.7 W and weight <15 g. Both share the same compact size, interfaces, algorithms, and environmental performance.
