Since 1993 Hamamatsu Photonics have offered a wide range of CMOS linear image sensors for use in analytical instruments such as spectrophotometers and industrial process monitoring equipment. A new range of CMOS linear image sensors has recently been developed, which offer very high-speed response whilst maintaining high resolution.

The new S11105 series offer “industry leading” ultra high-speed readout of up to 50 MHz. 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 50 MHz, the S11105 includes an electronic shutter function to facilitate accurate high speed imaging.

The new S11105 series has 512 pixels with a 12.5 µm 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, making system design and implementation easier than ever! The S11105 series are also available in two versatile packaging types; dual in-line (DIL) and surface mount options.

The S11105 series are ideal 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.
