PI0256WSN

Peripheral Imaging Corporation's WSN series is family of self-scanning photodiode solid-state linear imaging arrays. These photodiode sensors employ PIC's proprietary CMOS Image Sensing Technology to integrate the sensors into a single monolithic chip. These WSN series  sensors are optimally designed for applications in spectroscopy. Accordingly, these sensors contain a linear array of photodiodes with an optimized geome geomet- rical aspect ratio (50- mm aperture pitch x 2500- m mm 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 pinout config configu- ration is seen in Figure 1.
