SensL has introduced a position-sensitive multianode silicon photomultiplier array for positron emission tomography, radiation detection for medical and security purposes, and fluorescence applications that require very sensitive detector arrays. The device is an arrayed version of the company’s silicon photomultiplier pixels tiled together using flip chip technology on glass and is sensitive to visible light in the 400- to 850-nm range. It is mounted in a low-profile housing and includes a Molex board-to-board connector through which the output signal of each pixel is addressed separately. The standard version has 16 channels and a total area of 1.3 × 1.3 cm, and it can be customized in 1- and 2-D array formats. Rise time is <5 ns, and gain is 106.
