- 1 mm sensor, which a choice of microcell size
- Evaluation board with either SMA connectors or pins are available
The R-Series is a new range of Silicon Photomultipliers (SiPM) providing increased sensitivity into the red and NIR region of the electromagnetic spectrum. The current release from the R-Series is the RB-Series of sensors that provide improved photon detection efficiency and reduced crosstalk over the previous RA-Series. The RB-Series 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 molded 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-Series SiPM sensors is for LiDAR and ranging applications that use 905 nm light. 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.
Detailed product information can be found in the RB-Series datasheet. It is strongly recommended that those new to SiPM sensors consult the Introduction to Silicon Photomultipliers Tech Note.
An R-Series monolithic 1 x 16 SiPM array designed specifically for automotive LiDAR applications is also available. More information on the ArrayRA-0116A20 product is available on this page and in the datasheet. The product is also now available on the eStore.
