FOTRIC · S4
FOTRIC TK6 (L25) 384 × 288 native pixels. Advertised NETD: 40 mK.
Add to comparison Reference configuration: L25 lens, 25° × 19°, manual focus from 0.15 m (the product description also mentions close-up images from 10 cm). FOTRIC's datasheet gives 384 × 288 at 17 µm; one retailer listing still shows 320 × 240 and -20 to 450 °C, which contradicts the manufacturer and was not used. Removable 5000 mAh battery, over 4 hours of continuous use.
