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
