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. CONSTRUCTION
•

•
different package versions
(TO5 with/without IR-blocking)
•
dielectric filters for the three colour ranges: red, green and blue
•
Electrical connections
−
three anodes
−
one common cathode
