Stil, inventor and manufacturer of the chromatic confocal distance sensor (CCS), has added a 'double frequency' function to the CCS Prima range of point sensors.
This innovative function allows the sensor to simultaneously work with two different frequencies, in order to optimise the quality of the measurement at each point of the analysed surface.
The technology allows the CCS sensors to produce a high resolution surface profile of a sample, and the use of a simultaneous second frequency means that the sensor will work well on heterogeneously reflective materials. Heterogeneous sample surface reflectivity can be a problem for single frequency solutions, reducing the accuracy of measurments.
The confocal distance sensors are intended for use in sensing the roughness, the thickness or the microtopography of a surface, and can be used for applications such as auto-focus and in-line industrial control.
