Measuring Software (CALIGO) by Carl Zeiss Industrielle Messtechnik GmbH

The complete program for freeform surfaces and more.

CALIGO, the new software for freeform surfaces, makes the measurement of car body parts easier and faster than ever. The completely new software architecture provides highly efficient tools for analysis measurements, serial measurements, simulations and reporting.

Successor to HOLOS

CALIGO replaces HOLOS software. Switching from HOLOS to CALIGO is amazingly simple: measurement plans programmed in HOLOS can be easily imported into CALIGO. Furthermore, CALIGO integrates seamlessly into Carl Zeiss’ current software portfolio. By focusing on the measurement of freeform surfaces, CALIGO is primarily intended for users in car body construction. With CALIGO, they receive a total solution that enables them to intuitively measure standard geometries in the same way as freeform surfaces. CALIGO is easy to use, has a short familiarization period, and offers powerful data processing tools and many new functions that simplify quality assurance.

New software technologies

Carl Zeiss turned to the latest software development technologies for CALIGO. For example, a modular system architecture offers the flexibility needed for the requirements of tomorrow. Optimum use of the available system resources means that extensive measurement data is available more quickly with CALIGO. The CALIGO user interface enables the operator to intuitively use the measuring software. This reduces the familiarization period and promotes acceptance of the new software.

Change management

The change management function in CALIGO increases efficiency enormously: feature lists common in quality inspection can be imported in CALIGO and saved directly as measurement plans. If a feature list changes, the synchronization function enables the user to compare it with the current measurement plan. Every modification is shown to the user, who can then decide if he wants to accept the change or make additional modifications. The change management function in CALIGO enables users to respond to changes quickly and flexibly, and to integrate modified items into their measuring process without further delay.


The simulation function now available in CALIGO provides users with an extensive array of tools to analyze the measuring program before the real sequence starts: the measuring run is shown as a virtual animation in the CAD window. Functions such as collision control, travel path track and collision ball help them optimize programming or detect and eliminate errors. Various horizontal arm measuring machines and duplex systems can be completely simulated in CALIGO. The EagleEye optical sensor has also been taken into consideration. It is now possible to set up a run with EagleEye offline.

Safety sheath

CALIGO can generate travel paths automatically to prevent collisions with the workpiece. CALIGO independently finds the path from feature to feature. Furthermore, the new “Path in / Path out” navigation function is integrated into CALIGO. This enables users to program a safe path into and back out of an interior space. Certain features from an extensive measurement plan or new features can be programmed quickly and measured reliably.

Evaluation and reporting

CALIGO makes it possible to generate CAD result displays as false-color illustrations or with result flags in the measurement plan. These views can then be incorporated into a measurement log. CALIGO has a library of standard templates for fast log output. The integrated editing module in CALIGO enables users to design logs and templates in accordance with corporate guidelines.


The CALIGO DMIS option for CALIGO allows you to create, edit, save and run DMIS measurement plans. The procedure for DMIS measurement plans is similar to that for normal CALIGO measurement plans.
