| www..com DATA-SHEET MCS3AT/BT 3-element colour sensor - TO5 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 different package versions dielectric filters for the three colour ranges: red, green and blue (TO5, with/without IR-blocked) Electrical connections - three anodes - one common cathode Distributor: Laser Components Instrument Group, Wilmington MA, Phone: 978 658 9100, www.laser-components.com The information disclosed herein was originated by and is the property of MAZeT.

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. (for example the pin-programmable transimpedance amplifier MTI04 with the resistors 25k, 500k VOut and 5M) Ired MAZeT R1 Vred R2 +VR Igreen Vgreen MCS3 Iblue R3 Vblue Rx I Photo MTI04 APPLICATION NOTE It is recommended to use an IR-block filter > 720nm (MCS3BT) or a light source with low infrared radiation for optimal operations of the colour sensor.
