Hamamatsu has introduced its S11105 series of ultra high-speed CMOS linear image sensors, capable of readouts at 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 at 50MHz, the S11105 includes an electronic shutter function to facilitate accurate high speed imaging.
The new S11105 series has 512 pixels with a 12.5µm pitch giving an aspect ratio of 20:1, thus allowing 20 times the light collection area compared to conventional linear CCDs. This provides the user with much greater sensitivity.
The new 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, facilitating system design and implementation. The S11105 series are also available in two versatile packaging types; dual in-line (DIL) and surface mount options.
The S11105 series are suitable for applications such as in-line product inspection, portable spectrometers, industrial process control, colour monitoring, medical diagnostics, distance measurement, optical encoders, blood analysers, optical scanners, water pollution analysers and many more.
