The circular sensor ACS2 is used for colour measurement of structured and highly reflective surfaces as well as lustrous metals. The colour impression of painted or woven surfaces often depends on the viewing angle. This not only applies to the human eye but also to sensors.
The new ACS2 circular sensor illuminates the measurement surface in a 360° circular manner and provides exact measurement results independently of the working direction, even on difficult surfaces such as metallic paint. In the sensor, 24 lighting optics are circularly arranged around the receiving optics and provide a constant homogeneous lighting permitting that the measurement can be executed independently from the angular position of the measurement object.
This sensor enables as well to measure small measurement objects and curved surfaces. The measurement spot diameter is 5mm; 9mm is also available as an option. The optimal measurement distance is 28mm.
