OKS4001‑B4‑650# is high‑performance 3MP ultra‑low‑distortion M12 board lens, specially designed for facial recognition terminals, access‑control door locks and time‑attendance camera modules. Adopting premium 4E+1IR optical construction with multi‑layer broadband anti‑reflection coating, it delivers high light transmittance and effectively suppress ghost image and stray‑light interference. The ultra‑low distortion below ‑0.1% avoids facial stretching and deformation, critical for high‑accuracy AI face algorithm matching.
2.4mm wide‑angle focal length provides max 130° diagonal field‑of‑view with large Ø7.4 mm image circle, which can capture multiple human faces in a single frame. F2.0 large aperture ensures clear imaging under dim indoor entrance lighting conditions. Short total track length 15.59 mm and compact barrel Φ14*12.75 mm are ideal for slim facial‑recognition terminal assembly. Wide operating temperature‑20℃~+80℃ and RoHS‑compliant material guarantee reliable performance for access‑control door, time‑attendance machine, gate‑way facial‑recognition equipment OEM mass‑production.
