400-1100nm 四象限Si光电探测器(N型硅象限探测器光敏面直径16mm 直流响应度0.3A/W)

The device is an N-type silicon quadrant detector. When the radiation flux of light radiating to each quadrant of the device is equal, the photocurrent output of each quadrant is equal. When the target is offset, the change of radiation flux between quadrants causes the change of output photocurrent of each quadrant, thereby measuring the direction of the object, thus playing the role of tracking and guiding.

产品特点：Low dark current、 High uniformity and symmetry、 High reliability、 Small blind spot

应用领域：Laser aiming, guidance, tracking and exploration device、 Precision measurement system such as laser micro-positioning and displacement monitoring
