Low Noise, Red-Sensitive Silicon Photomultipliers
The R-Series is a new family of Silicon Photomultiplier (SiPM) sensors providing sensitivity into the red and NIR portion of the spectrum. The R-Series SiPM sensors feature high responsivity, fast signal response, and a low temperature coefficient, all achieved at a low operating voltage. The sensor is packaged in a compact and robust MLP package that is suitable for reflow solder processes. Both the sensor and the package are designed for volume production, with the product delivered on tape and reel. SiPM sensors are a type of avalanche photodiode (APD) that is operated in the Geiger mode. Unlike the similarly-operated SPAD that can only detect single photons, the SiPM overcomes these limitations by incorporating a ‘microcell’ structure over the active surface. It is strongly recommended that those new to SiPM sensors consult the Introduction to Silicon Photomultipliers Tech Note.
