RB-SERIES SIPM: Silicon Photomultipliers, NIR-Enhanced

The RB-Series is a range of Silicon Photomultipliers (SiPM) providing increased sensitivity into the red and NIR region of the electromagnetic spectrum. The RB sensors feature single photon sensitivity, high responsivity and fast signal response, all achieved at a low bias voltage. The sensor is packaged in a compact and robust micro leadframe package (MLP) that is suitable for reflow solder processes. Both the sensor and the package are designed for volume production, and are delivered on tape and reel.

The primary application for the RB SiPM sensors is for LiDAR and ranging applications. These SiPM sensors are an improvement over avalanche photodiodes (APD) and PIN diodes due to their high gain and single photon sensitivity. For LiDAR applications, this enables the detection of low reflectivity targets at very long distance. Unlike the similarly-operated SPAD that can only detect single photons, the SiPM overcomes this limitation by incorporating a ‘microcell’ structure that allows for multi-photon detection with a high dynamic range.
