Industrial Metrology Firm Introduces Chromatic White Light Sensor Family

12 August 2016

Carl Zeiss Industrial Metrology 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 Zeiss Accura multisensor coordinate measurement machines. With the new solution, customers can scan complex parts from all sides in one measuring run—thanks to the combination of the Accura with articulating RDS measurement head and the new DotScan sensor. Zeiss will introduce the first three members of the DotScan sensor family at the International Manufacturing Technology Show in Chicago, September 12–17, 2016.

In addition to savings in measurement time, the company says the DotScan family also enables users to measure highly reflective, free-form surfaces. Previously a certain measuring range of the sensor was exceeded because the workpieces had to be rotated manually. The new sensor family is available on the Accura multisensor coordinate measuring machine, which enables the fully automatic exchange of the Zeiss DotScan during a computer numerical control (CNC) run.

Reaching beyond limitations

Zeiss touts the DotScan as an excellent option for measuring free-form surfaces and minute structures, calling the embedded chromatic white light sensor the method of choice for sensitive, soft, reflective or low-contrast surfaces, which create problems for traditional styli or camera sensors. According to Zeiss, strongly reflective surfaces, such as metal components in knee implants, can be measured using DotScan without the need for a contrast medium. Now transparent lacquered surfaces can be distinguished from other underlying metallic layers, the company says.

Flexibility in range and angle

Zeiss DotScan is available in three different measuring ranges: 10 mm, 3 mm and 1 mm. Each sensor can be fully, automatically exchanged with other Zeiss contact or optical sensors within 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 because the maximum measuring angle of the Zeiss DotScan is plus or minus 30°, critical dimensions on strongly curved components can now be measured.
