Principle of operation for CCS Technology 




STIL’s Chromatic Confocal modular optical heads series is the perfect balance of technology and precision. In order to optimize the choice of your sensor, it is essential to begin by choosing your optical pen according to your accuracy and measuring range needs. The optical pen or optical probe is the measuring head of the sensor. It is connected to the controller via an optical fibre. The various optical pens are defined by different measuring ranges and resolutions. A single controller can work with several optical pens.
Chromatic Confocal technology is the optimized solution to produce different types of high-accuracy measurement. Each optical pen has a different working distance, spot size on the target and angular opening of the light beam. The use of optical pens allows STIL’s technology to be completely contact free, a district advantage over CMM Probes, which can alter or deform the target during measurements. With the right choice of measurement set up there is no need to refocus the light beam on the target for a series of measurements on identical objects. As chromatic confocal optical pens do not require any energy sources and do not have moving parts, they are, in principle, unalterable and do not require a reset or a zero-setting during a series of measurement.

STIL – DUO dual technology controller (Chromatic Confocal and Interferometric)

STIL have recently expanded their product portfolio to include a white light interferometer, for applications not suited to their classic range of instruments using their patented chromatic confocal sensors. By combining both techniques into a single instrument they can cover an unrivalled range of sample types, including

  • measurement of thicknesses which are too thin to be measured with a classic chromatic confocal sensor
  • measuring the shape of samples as TSV (Through-Silicon Via) which present a very high ratio depth/diameter

The use of white light interferometry frees the system from the disadvantage of laser based interferometry, which are inherently highly sensitive to vibrations, airflow and sudden movements.
