Series 9 APDs from First Sensor are optimized for LiDAR applications
First Sensor's Series 9 offers a wide range of silicon avalanche photodiodes (APDs) with high sensitivity in the near infrared (NIR) wavelength range, especially at 905 nm. With their internal gain mechanism, large dynamic range, and fast rise time, the APDs are ideal for LiDAR (light detection and ranging) systems for optical distance measurement and object recognition according to the time of flight method. Application examples include driver assistance systems, drones, safety laser scanners, 3D-mapping, and robotics.
The Series 9 offers detectors as single elements as well as linear and matrix arrays with multiple sensing elements. The package options include rugged TO housings or flat ceramic SMD packages. The slow increase of the gain of the Series 9 photodiodes with the applied reverse bias voltage allows for easy and precise adjustments of high gain factors.
For particularly low light levels, hybrid solutions are also available that further enhance the APD signal with an internal transimpedance amplifier (TIA). The integrated amplifier is optimally matched to the photodiode and allows compact setups as well as very large signal-to-noise ratios.
First Sensor can adapt its silicon avalanche photodiodes to specific customer requirements such as sensitivity, gain, rise time, or design.
