Hamamatsu Photonics has developed the S11105 series of CMOS linear image sensors for use in in-line product inspection, portable spectrometers, industrial process control and more. The CMOS linear image sensors are also suitable for colour monitoring, medical diagnostics, distance measurement, optical encoders, blood analysers, optical scanners and water pollution analysers. The S11105 series offers an ultra-high-speed readout of up to 50MHz.

This pixel data rate is achieved via a single output video line, unlike conventional high-speed CCDs that use multiple output video lines (or taps) to achieve higher-speed operation. In addition to the high-speed readout, the S11105 includes an electronic shutter function to facilitate accurate high-speed imaging. The series has 512 pixels with a 12.5um pitch, giving an aspect ratio of 20:1, therefore allowing 20 times the light collection area compared with conventional linear CCDs.

This is said to provide the user with much greater sensitivity. The device incorporates 512 individual photodiode elements with buffer amplifier, digital shift register and signal processing circuit all on the same 'monolithic' silicon chip. All of the necessary clock generation functions are provided on chip, simplifying system design and implementation. The S11105 series is available in two versatile packaging types: dual in-line (DUL) and surface-mount options.
