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 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.
2 APPLICATION
Quality control
Monitoring the production
Control of manufacturing
Detection of colour marks
3 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)
4 CONSTRUCTION
3 on chip integrated PIN photo diodes
package version TO5, with optical lense

The optical lens allows the light collection at a
acceptance angle width from 25. In this case, the
optimal work distance is 2 to 6 cm. The use of greater
work distances is to be adapted by larger illumination
intensity level.

9 APPLICATION CIRCUIT
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.
(for example the pin-programmable
transimpedance amplifier MTI04 with the
resistors 25kW, 500kW
and 5MW)
10 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.
