Solid-state silicon photomultipliers offer performance and application advantages
First Sensor extends its range of optical sensors with innovative
solid-state silicon photomultipliers (SiPMs) for the detection of
ultra-low light levels down to single photons. Compared to conventional
photomultiplier tubes, SiPMs offer significant advantages such as low
operating voltage, excellent temperature stability, immunity to magnetic
fields and a much smaller size for easy system integration. The
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.
The silicon photomultipliers consist of a matrix of multiple
avalanche photodiode (APD) micro-cells operated above their breakdown
voltage (Geiger mode). NUV- and RGB-SiPMs from First Sensor feature
extremely low temperature coefficients of the breakdown voltage and
gain, which allows for highly accurate and stable measurements. Enhanced
materials and semiconductor technology enable low-noise devices with
reduced dark count rate, crosstalk and very low afterpulsing probability
typ. 106) and high photon detection efficiencies.
The edgeless SiPM dies ensure high cell fill-factors and maximized
active areas in array arrangements. The Chip-Scale-Package (CSP)
provides a cost-effective and RoHS compliant solution suitable for
reflow soldering. For custom specific applications First Sensor develops
and manufactures arrays, modules and complete systems for OEM customers
worldwide.
Important features of the SiPM-NUV and SiPM-RGB silicon photomultipliers:

• Ultra-low light detection down to single photons
• Low operating voltage
• High gain and low noise
• Immunity to magnetic fields

Typical applications of silicon photomultipliers from First Sensor
include high energy physics, medical diagnostics, nuclear medicine,
homeland security and analytical instruments. Due to the immunity to
external magnetic fields, SiPM detctors are ideal for medical imaging
applications such as combined tomography systems using magnetic
resonance tomography (MRT) and positron emission tomography (PET) or
single photon emission computed tomography (SPECT).
