50µm-pitch Wide Aperture Spectroscopic Photodiode Arrays
Data Sheet
1.0 Description
AMI Semiconductor’s WSN series is a family of self-scanning photodiode solid-state linear imaging arrays. These photodiode sensors
employ AMI Semiconductor’s proprietary CMOS image sensing technology to integrate the sensors into a single monolithic chip. These
sensors are optimally designed for applications in spectroscopy. Accordingly, these sensors contain a linear array of photodiodes with
an optimized geometrical aspect ratio (50µm aperture pitch x 2500µm aperture width) for helping to maintain mechanical stability in
spectroscopic instruments and for providing a large light-capturing ability. The family of sensors consists of photodiode arrays of
various lengths - 128, 256 and 512 pixels.
The WSN photodiode arrays are mounted in 22-pin ceramic side-brazed dual-in-line packages that fit in standard DIP sockets. A
diagram of its pin out configuration is seen in Figure 1.
