Sensor Family Shines White Light on the Subject

"Transparent or highly reflective surfaces are no problem for the ZEISS DotScan. When mounted on the RDS articulating probe head, the ZEISS DotScan sensor can reach all areas of the part without difficulty," said a company spokesperson.

ZEISS has announced a new solution for dimensional measurement of freeform surfaces on sensitive, soft or low-contrast materials. The new ZEISS DotScan family of chromatic white light sensors is now available on new ZEISS ACCURA multisensor coordinate measurement machines. Customers can scan complex parts from all sides in one measuring run due to the combination of the ACCURA with articulating RDS measurement head and the new DotScan sensor.

"Not only does the ZEISS DotScan family save customers time in measurement, it also enables them to measure highly reflective freeform surfaces. Previously, a certain measuring range of the sensor was exceeded because the workpieces had to be rotated manually. The new sensor family is now available on the ZEISS ACCURA multisensor coordinate measuring machine (CMM), which enables the fully automatic exchange of the ZEISS DotScan during a CNC run," said the spokesperson.

ZEISS DotScan is an option for measuring freeform surfaces and minute structures. "The embedded chromatic white light sensor is the method of choice, especially when traditional styli or camera sensors reach their limits on sensitive, soft, reflective or low-contrast surfaces. By using ZEISS DotScan, strongly reflective surfaces, such as metal components in knee implants, can be measured without the need for a contrast medium. Now, transparent lacquered surfaces can be distinguished from other underlying metallic layers," said the spokesperson.

ZEISS DotScan is available in three different measuring ranges: 10, 3 and 1 mm. Each sensor can be fully automatically exchanged with other ZEISS contact or optical sensors inside a single CNC run. With 20,736 possible orientations, the articulating RDS measurement head can align the ZEISS DotScan perpendicular to surfaces of the part being measured. And since the maximum measuring angle of the ZEISS DotScan is +/- 30°, critical dimensions on strongly curved components can now be measured.
