4W 850nm VCSEL Laser Diode
VCSEL devices are widely used in 3D face recognition and distance sensing. When VCSEL arrays are used in TOF modules, especially dTOF systems such as LiDAR, the peak power, operating current, operating voltage, conversion efficiency, near-field and far-field optical characteristics of VCSEL in narrow pulse conditions are very important.
