New Fast and Compact Color Sensors from
For industrial color applications with
high dynamics, these new compact
color sensors are a preferred choice.
Three areas, each of different color,
are responsible for the recognition -
similar to the human eye.
Color sensors based on Si-PIN-diodes
and dielectric filters on-chip feature a
small design, high-quality filters and
the synchronous recording of all three-
color ranges. Furthermore, the circular
alignment of the diodes allows simple
coupling of the measurement signal
using an optical fibre. The sensors are
offered in the TO5 package with trans-
lucent plastic or cover glass and/or in
the SOP8 with translucent plastic.
The color sensors are made of 3 Si-
PIN photo diodes integrated on chip.
Each of these photodiodes is sensi-
tized with a dielectric spectral filter
for its color range, preferably for the
primary colors red, green and blue.
By direct mounting of the spectral
filters onto the photodiodes, the sen-
sor is a highly compact component.
As a result, measuring systems
based on this sensor can be sized
considerably smaller than traditional
color measuring instruments.
The 3-element color sensors require
only 3 measured values. These are
detected simultaneously for deter-
mining the color. As a result, the
three field sensors allow for low-cost
and fast signal processing. The Si-
PIN photo diode design allows signal
frequencies up to the MHz-range.
