DATA-SHEET MCSi Integral 3-Element Colour Sensor 1. FUNCTION The colour sensors are made of 19 x 3 Si-PIN photo diodes integrated on chip. They are carried out as a hexagonal matrix with the diameter of 3 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 have been separated from each other by additional structures. Each of these photodiodes is sensitized with dielectric spectral filter for its colour range, preferably for the primary colours red, green and blue. 2. APPLICATION • • • • Quality control Monitoring the production Control of manufacturing Detection of colour marks 3. FEATURES Dielectric filters guarantee 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. 3 mm) − insensitiveness to decentralized imaging, e. g. LWL coupling 4.

APPLICATION CIRCUIT MAZeT Opposite figure shows a circuit for the conversion of photo current to an equivalent voltage. These voltage can be processed e.g. with an ADC. By the selection of suitable resistors the output voltage range can be adjusted to the photo current value.

APPLICATION NOTE It is recommended to use an IR-block filter > 720nm or a light source with low infrared radiation for optimal operations of the colour sensor. 11.
