1. 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 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. 2 mm)
4. CONSTRUCTION
• 3 on chip integrated PIN photo diodes
• dielectric filters for the three colour ranges: red, green and blue
• package design SOP8
• Electrical connections
−
three anodes
−
one separated diode for minimization of the cross-talk
−
one common cathode
