ZEISS has accepted the technical challenges resulting from these requirements and has taken advantage of its many years of development work, its in-depth discussions with customers and the permanently increasing quality requirements to offer a new generation of optical measuring machines. ZEISS Optical Series consists of models tailored to meet customers‘ requirements, each version of which is equipped with variable illumination, a high-resolution camera and sophisticated software; each machine is capable of delivering rapid and accurate measurement readings. The range of models extends from purely optical machines to multi-sensor solutions, in which components can be measured both optically and by tactile techniques in one and the same machine.
Entry into the world of modern optical metrology has never been so simple. Thanks to a clear-cut design and an intuitive user interface, operation of the newly developed ZEISS O-DETECT is child‘s play after a short training even for newcomers to the machine. The purely optical measuring machine provides contact-free measurement and delivers rapid and precise data in no time.
The high-performance, high-resolution optical system and digital zoom, an overview camera for easy navigation and an adjustable ring light are amongst the equipment responsible for the precise measurement readings. ZEISS software also guarantees not only a precise analysis of the optically collected data but also an optimal user experience.
The purely optical ZEISS O-DETECT coordinate measuring machine proves just how simple the operation of a highly-technical machine can be made for the user. Thanks to the intuitive, easily grasped user interface, after only a 2-day training even staff new to ZEISS O-DETECT can reliably operate this machine, which has been optimized and automated for simple use. Users achieve accurate measurement readings right from the start.
The high-quality camera is a vital part of ZEISS O-DETECT. The complete lack of optical distortion of any kind creates the technical foundation needed for precise measurements. Thanks to sophisticated software and the new auto-focus function, the photographic data recorded by the camera is transformed into precise measurement results at the touch of a button.
When accurate measurement results are at stake, first-class illumination plays a pivotal role. The two versatile ring lights, which are easily replaceable by hand, meet this need. The white and the blue ring lights operate both automatically as well as in line with user-defined settings. The customer himself can easily install updates and upgrades without any need to call a service team.
For the first time an overview camera with an integral 5 megapixel camera sensor also forms a further standard component. As a result, the component due for measurement can be located faster and an image can be created within a short period of time.
This gives the user an easier overview of all the scanned parts. As with other applications, this technical component excels with its particularly simple and fast control system.
ZEISS O-INSPECT gives the user the best of both worlds in just a single machine - the optical measuring machine with a tactile sensor provides the opportunity for the precision measurement of the broadest possible variety of components both optically and using tactile technology without the need for recalibration when changing the sensor technology, as both technologies are integrated into a single machine. When dealing with complex components, this machine saves not only time and money but also reduces the risk of inaccurate measurements caused by the use of different machines.
Thanks to the continuous development of multi-sensor technology - for example ranging from high optical resolution created by alternative sensor units which make the error-free measurement of extremely small structures possible, through to a particularly sensitive tactile scan-sensor – ZEISS O-INSPECT never fails to generate accurate 3D measurement results in compliance with ISO-10360.
Thanks to an updated software solution, measurements up to 6x faster than before are possible. Faster programming is possible for the user and several features of the component can be measured precisely at the same time. The updated software used in ZEISS O-INSPECT is therefore not only extremely user-friendly but, above all, it also saves additional costs for the customer.

Since May 2015, the Measurement and Calibration Center of Carl Zeiss Industriellen Messtechnik GmbH with its locations in Essingen and Oberkochen, Germany, has been accredited for the calibration of length standards for optical metrology. The measuring method is based on the use of the ViScan 2D image processing sensor on bridge-type measuring instruments from ZEISS and enables calibration in a 2D measuring range of 1200 mm x 1980 mm with an uncertainty of 0.7 μm + 2 x 10-6 x L. By using a ZEISS O-INSPECT measuring device, it was possible to successfully extend accreditation in the high-precision range.
Since February 2019, chromium masks can now also be calibrated in the nanometer range. The smallest uncertainties for unidirectional distances are 0.09 μm + 0.14 x 10-6 x L, for diameters 0.25 μm and roundness deviations 0.3 μm.
René Friedel also proudly points out the unrivalled capabilities of the ZEISS Measuring and Calibration Center: “We are currently the only laboratory in all of Germany that can offer calibration of length, diameter, form deviation and the thermal expansion coefficient on optical standards from a single source - from microstructures with smallest diameters of 0.06 mm to a large-volume 2D measuring range”. In May 2020, the accreditation for onsite calibration of coordinate measuring machines with optical 2D image processing sensor will be extended. “This gives us the authority to verify the measuring accuracy of machines according to the DIN EN ISO 10360- 7 standard and to certify it by means of DAkkS calibration”.
The following figures underline how important accreditations for equipment in the field of metrology have become in the meantime. While 10 years ago there were only 25 accredited on-site calibrations of measuring instruments, the number has already risen to the four-digit range in 2019. Especially in the automotive industry, the demand is constantly increasing. The ZEISS team is ideally equipped for this: “In dimensional metrology, we are currently one of the most accurate calibration laboratories in the world. This not only benefits our own development work, but it also benefits all customers who want to have their optical standards and machines calibrated and checked by us.”
