第一传感器将其光学传感器的范围扩展到具有创新的固态硅光电层流(SIPM),以检测到单个光子的超低光级别。与常规的光电倍增管相比,SIPMS提供低工作电压,温度稳定性,对磁场的免疫力和尺寸较小,以便于系统集成。检测器针对近距离紫外线(SIPM-NUV)或红色,绿色和蓝色(Seripm-RGB)光检测进行了优化,其峰值敏感性在420 nm或550 nm处。
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 have low temperature coefficients of the breakdown voltage and gain. Enhanced materials and semiconductor technology enable low-noise devices with reduced dark count rate and crosstalk. The edgeless SiPM dies ensure high cell fill-factors and maximized active areas in array arrangements. The Chip-Scale-Package (CSP) provides an 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.
SIPM-NUV和SIPM-RGB硅光电层的重要特征:
超低光检测到单光子
低工作电压
High gain and low noise
Immunity to magnetic fields
第一传感器的硅光载体的典型应用包括高能量物理,医学诊断,核医学,国土安全和分析仪器。由于对外部磁场的免疫力,SIPM替换器非常适合使用磁共振断层扫描(MRT)和正电子发射断层扫描(PET)或单光子发射计算机断层扫描(SPECT)的医学成像应用,例如合并的断层扫描系统。
