JENCOLOUR® - RGB Colour Sensors The Smallest Tri-Colour Sensors Of The World
PRODUCT INFORMATION
Fast and compact colour recognition based upon silicon photodiodes with interference filters integrated on chip!
For industrial colour applications with high dynamics the new compact colour
sensors are a preferred choice. Three areas, each of different colour, are responsible for the recognition - similar to the human eye. Colour
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 as default in the TO5 package with translucent plastic or cover glass and/or in the SOP8 with translucent plastic. The colour
sensors are made of 3 Si-PIN photo diodes integrated on chip. Each of these photodiodes is sensitized with an interference spectral filter for its colour range, preferably for the primary colours red, green and blue. By direct mounting of the spectral filters onto the photodiodes, the
sensor is a highly compact component. As a result, measuring systems based on this
sensor can be sized considerably smaller than traditional colour measuring instruments. The 3-element colour
sensors require only 3 measured values. These are detected simultaneously for determining the colour. As a result, the three field
sensors allow low-cost and fast signal processing. The Si-PIN photo diode design allows signal frequencies up to the MHz-range.
Highlights
Can be matched to customer requirements MHz signal frequency for taking measurements where time is critical Steep slope of filter curves Simple coupling of the measuring signal, e.g. with the help of a glass fibre by means of 3-element structure Colour and location information by means of integral structure
