First Sensor's new solid-state silicon photomultipliers (SiPMs) are designed to detect ultra-low light levels down to single photons. These detectors are optimized for near-ultraviolet (Series SiPM-NUV) or red, green, and blue (Series SiPM-RGB) light detection with peak sensitivities at 420 nm or 550 nm.
These SiPMs are comprised of a matrix of multiple avalanche photodiode (APD) micro-cells that operate above their breakdown voltage. Both the NUV and RGB series feature extremely low temperature coefficients of the breakdown voltage and gain, which permits stable and highly accurate measurements. These devices are housed in a Chip-Scale-Package (CSP), offering a cost effective and RoHS compliant solution suitable for reflow soldering. Typical applications include energy physics, medical diagnostics, nuclear medicine, homeland security, analytical instruments, and medical imaging.
