| DATA-SHEET MCS3AO 3-element colour sensor - TO5 with optics FUNCTION The colour sensors are made of 3 Si-PIN photo diodes integrated on chip. They are carried out as segments of a ring with the diameter of 2,0 mm. The design as Si-PIN photo diodes allows signal frequencies up to MHz-range. In order to achieve a small cross talk between the photodiodes the individual sectors were separated from each other by additional structures. Each of these photodiodes is sensitised with dielectric spectral filter for its colour range, preferably for the primary colours red, green and blue. APPLICATION * * * * Quality control Monitoring the production Control of manufacturing Detection of colour marks FEATURES Dielectric filters guaranties the good optical properties of the colour sensors, such as: - high transmission - slight aging of the filter - high temperature stability - high signal frequency - reduced cross talk - small size (diameter of the optical sensitive surface ca. 2 mm) CONSTRUCTION * * * * 3 on chip integrated PIN photo diodes package version TO5, with optical lense dielectric filters for the three colour ranges: red, green and blue Electrical connections - three anodes - one common cathode Germany and other countries: LASER COMPONENTS GmbH, Phone: +49 (0)8142 28640, Fax: +49 (0)8142 286411, info@lasercomponents.com USA: LASER COMPONENTS Instrument Group Inc., Phone: +1 603 821 7040, Fax: +1 603 821 7041, info@laser-components.com Great Britain: LASER COMPONENTS (UK) Ltd., Phone: +44 1245 491 499, Fax: +44 1245 491 801, info@lasercomponents.co.uk The information disclosed herein was originated by and is the property of MAZeT.

In this case, the optimal work distance is 2 to 6 cm. The use of greater work distances is to be adapted by larger illumination intensity level.
