1x64 Silicon APD Array Forecasts Next-Gen LiDAR Systems

(Excelitas Technologies)

Expanding the C30737 APD series avalanche photodiodes, Excelitas Technologies’ latest 1x64 Silicon APD for use in LiDAR applications provides a high 64-pixel count for higher-resolution systems, enabling better detection of objects around a vehicle in next-generation LiDAR systems. When paired with the company’s pulsed laser diode arrays, it enables a LiDAR system to detect reflected light that bounces off a target in front of the vehicle. Reportedly, this creates a high-resolution point cloud image of the surrounding area, enabling the vehicle to see and take appropriate action to safely navigate to its intended destination. The high-resolution 1x64 APD enables the use of smaller optics, reducing cost and providing better signal-to-noise ratio for longer-range detection, beyond the 200 meters required for safe forward-looking sensing.


The 1x64 Silicon APD is supplied in a compact surface-mount package, suitable for high-volume pick-and-place assembly lines. The product is available off-the-shelf or customized with pixel geometry, spacing and number of pixels to match the customer’s optical system. Electrical characteristics can also be customized to fit with the receiver electronics. For additional information, visit Excelitas Technologies.
