Series 9 Avalanche Photodiodes Offer High Sensitivity at 905 nm

First Sensor Inc. Apr 17, 2018

Press Release Summary:

Series 9 Avalanche Photodiodes are offered in TO housings or flat ceramic SMD packages. Units come with internal amplifier that is optimally matched to photodiode for high signal-to-noise ratios. Photodiodes are suitable for applications such as driver assistance systems, drones, safety laser scanners, 3D-mapping and robotics. Units are available as single element, linear and matrix arrays and can be used in low light levels with internal transimpedance amplifier (TIA).

Original Press Release:

Series 9 Offers Wide Range of APDs Optimized for LIDAR Applications

With the Series 9, First Sensor offers a wide range of silicon avalanche photodiodes (APDs) with very 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 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.

Thanks to its own semiconductor manufacturing facility and extensive development capabilities, First Sensor can adapt its silicon avalanche photodiodes to specific customer requirements, e.g. in terms of sensitivity, gain, rise time or design.

Important features of the Series 9 APDs:

Very high sensitivity at 905 nm
Large dynamic range and fast rise time
Single element photodiodes as well as linear and matrix arrays
Rugged TO housings or flat ceramic SMD packages
Hybrid solutions with integrated TIA
