Increased efficiency, greater flexibility and cost effective are some of the highlights of the organisation’s sensor technologies. The ZEISS Rotos and the ZEISS Dotscan are the next generation of roughness sensors.

The metrology market is expected to reach at 1255.5 million dollars by the end of 2027, according to a report by Market Research Future. ZEISS is one of the major players in the metrology segment and is keen to create technologies for greater efficiency and accuracy. The company has enhanced its sensor systems for faster, more flexible and more efficient measuring processes.


Utilised on coordinate measuring machines (CMMs), the new enhanced ZEISS Rotos roughness sensor offers one to carry out standard-compliant surface waviness and roughness inspections even on uneven or complex surfaces. The sensor also simplifies and speeds up the measurement of all surface parameters from the drawing in a single process step.

In addition to this, it also becomes possible for the user to check the size, form and location tolerances together with the roughness parameters on a single machine. Instead of requiring separate stylus instruments to capture more significant form deviations such as waviness or roughness, these can now be performed on a CNC-controlled CMM.

Flanked by three rotatable axes and multiple stylus arms, the sensor makes it convenient for the user to measure deep boreholes and difficult-to-reach surfaces. Tried and tested, the ZEISS Rotos proves to be the ideal system where the user can perform at-line roughness measurements as well as efficiently perform inspections on a single machine.

ZEISS Dotscan

Usually inspecting sensitive, reflective and low-contrast surfaces is difficult but the company states that now users can perform this task in a short period of time via the ZEISS O-Inspect multisensor measuring machine. The new systems will now be incorporated with an interface for the ZEISS Dotscan chromatic-confocal white light sensor beginning from May 2018.

The sensor is also convenient for users as now they can operate their multisensor measuring machine models with a switch which they can turn in or out as per their requirement. The plus point is that it leads to increased flexibility and also saves time.

For different measuring ranges, the sensor is available in three sizes – 1, 3 and 10 mm. Also, to obtain an improved effect with the ZEISS Dotscan for optical scanning one can make use of a rotary table on the ZEISS O-Inspect. The measuring speed of the sensor, which is dependent on several factors, ranges from 100 to 150 mm per second.

As the sensor can be integrated in all interfaces, the operator can insert the probing system in the measuring software and capture the data points on the component by making use of the standard ZEISS Calypso user interface without any difficulty.

Innovative technologies are always appreciated as it helps players from the industry to improve their product quality in a shorter period of time. With diverse new technologies, ZEISS is surely heading in the right direction!
