Comparison
F8 and F13M are both 640×512 uncooled VOx LWIR infrared FPA detectors widely used for drone thermal payloads.
F8 8μm IR Detector or F13M 12μm IR Detector: Which One Fits Your Drone Design?
by SkyVolt FPV Engineering Team · About the authors
Meta Description：
F8 features ultra-small pixel for miniaturized thermal payloads,
while F13m delivers superior NETD ≤30mK for weak heat source detection. Check our guide for UAV thermal imaging OEM selection.
The key difference lies in pixel pitch: F8 adopts 8μm pixel pitch for extreme SWaP optimization, while F13M uses 12μm pixels with better thermal sensitivity (NETD ≤30mK).
Your choice depends on the drone’s payload limit, working distance and mission type — compact close-range FPV applications prefer F8, and long-distance inspection, fire rescue and perimeter surveillance are better suited to F13M.
We stock both F8 and F13m . Feel free to contact our engineering team for datasheets, technical support and customized solution recommendations.
