The WYA-02B is an ultra-compact, micro-sized laser rangefinder module designed for high-precision integration where space and weight are severely constrained. Operating at a proven 905nm wavelength, this micro LRF module weighs 5g and measures just 22.5*16* 9.5mm, making it one of the most compact OEM ranging cores available in the 2026 optoelectronics market.
Despite its miniature footprint, the WYA-02B delivers robust performance, capable of ranging buildings up to 1200m and human targets up to 500m. It is the ultimate SWaP (Size, Weight, and Power) optimized solution for next-generation UAV gimbals, thermal sights, and portable consumer/industrial optical instruments.
With a weight of less than 5 grams, it eliminates payload penalties for micro-UAVs and wearable optical devices.
Offers an incredible accuracy at short range with an ultra-short blind spot.
Features high target acquisition success rate and low false alarm rate.
Support single measurement, 1Hz and 2Hz continuous measurement frequency to adapt to both static and dynamic tracking scenarios.
