Optical high-resolution measurements of miniature size and form features on challenging surfaces

Optical measurement of microgeometries and sensitive surfaces

Need to measure microgeometries on sensitive surfaces?

Use high-resolution optical sensors for parts that cannot be touched.

Would you like to know more?

Equipped with a chromatic white light sensor as standard, GLOBAL Optics is ideal for non-contact measurement of the geometric size and form characteristics of sensitive workpieces that cannot be touched and those with particularly challenging surfaces.

An indexing probe head provides excellent access to part features from almost any angle and direction, allowing optimal alignment of the chromatic white light sensor to the measured surface. Furthermore, in combination with an automatic sensor changer rack, and thanks to Hexagon’s opto-mechanical sensor interface, different sensors can be easily exchanged on the indexing probe head, maximising the CMM’s multisensor flexibility.

Typical applications


Application challenges

Non-contact size and form measurements on varied part surfaces

  • Soft and sensitive parts that cannot be touched
  • Very small geometries (microgeometries)
  • Varied materials and surface finishes: matte, transparent, reflective, microstructured, coated 

GLOBAL Optics benefits

  • Optical high-resolution measurement for capturing the smallest geometric structures
  • Single‑point distance measurement and scanning of freeform surfaces
  • Surface-independent measurements
  • Thickness measurements on transparent materials

Options tailored to individual application needs

Manufacturers can further tailor the capabilities of each base model GLOBAL Optics machine with options to meet their application needs best. A range of options can be selected during initial CMM configuration, and most can be set up later as upgrades to the in‑service machine.  


The Global Optics model can be equipped with additional sensors to make it suitable for a larger field of applications:

HP-C camera sensor
Optical measurements of small features and sensitive or easily deformed components

HP-S-X1 scanning probe
Compact tactile probe for highly accurate scanning applications


The XT (extended temperature) option allows the GLOBAL Optics model to be used in less controlled temperature environments, enabling accurate and reliable measurements near the production line without needing a costly climate room.


Accuracy+ reduces the CMM’s volumetric measurement error to the next level of accuracy and increases repeatability to address tighter part tolerances. The need for such capability is a growing trend in many industries.

At the same time, throughput is key to avoiding delays and ensuring parts are shipped on time. High measurement throughput is particularly important for near-line and 100% part inspection.

Throughput+ boosts measurement productivity of the GLOBAL Optics by significantly increasing the machine’s maximum measurement speed without compromising accuracy or precision.


Tabletop rotary tables for the GLOBAL Optics model enhance access to workpieces from any angle, so even highly complex parts can be measured quickly, with fewer probe changes, increasing throughput.


The GLOBAL Optics model can be equipped with various other options to get the most out of the machine for every application:

PULSE wireless real-time environmental monitoring
This system helps ensure measurement data integrity by notifying users of temperature, humidity, vibration, air pressure and luminosity changes that might affect measurement results.

Messaging lights
Messaging lights give operators the ability to monitor the machine’s status even from a distance, to optimise time and resource management.

Eco Mode+
The option reduces compressed air consumption by up to 90% when the machine is idle and saves up to 25% of compressed air costs under normal machine operating conditions.

Features and benefits 

GLOBAL CMMs are built on advanced design principles to inspire certainty and confidence. They combine quality components and state-of-the-art technologies for long-term stability, reduced measurement uncertainty, adaptability to harsh measuring environments, fast measuring point capture and an advanced user experience. These metrology solutions will provide manufacturers with maximum value over the entire lifecycle. 

Sturdy mechanical design 
The solid granite base with integrated dovetail guide guarantees long‑term system stability and consistent accuracy over the entire measurement volume.

Bridge with triangular crossbeam 
Featuring an improved stiffness-to-mass ratio relative to square or rectangular traverses, this design allows for the highest dynamics and high‑speed measurements. 

Preloaded air bearings on all axes 
Contactless, low-friction and low-wear axis motion ensures fast and repeatable positioning at all speeds and accelerations, resulting in low measuring uncertainties. 

Low-maintenance belt drive system 
Flat and V-ribbed belts ensure smooth and low-vibration axis motion. 

Temperature compensation 
Real‑time compensation of thermally caused measurement deviations through temperature sensing at the scales and on the workpiece ensures reliable measurement results. 

Extended temperature operating range (option) 
Measure your components with more resistance to environmental influences. An extended temperature operating range (15 - 30°C) allows the CMM to operate closer to the production line without needing a costly climate room. 

Real-time environmental monitoring (option) 
PULSE enables the user to monitor and log any environmental conditions surrounding the CMM and receive real‑time machine information.

Eco Mode 
Eco Mode supports sustainability and productivity goals by automatically powering down the CMM when idle, which improves energy efficiency while keeping the machine ready to go.

Messaging lights (option) 
Messaging lights give operators the ability to monitor the machine’s status even from a distance, to optimise time and resource management.

High-speed and safety 
Continuous monitoring of a defined safety area around the CMM allows worry-free high-speed measurement in CNC mode. The machine will slow down automatically when the user or an object encroaches upon the protected area. 

Multisensor versatility 
Using the widest range of tactile and optical sensors with Hexagon’s universal sensor interface, the CMM becomes a multisensor inspection device that can adapt to the most complex measuring tasks. 

Future-ready concept 
The future‑ready pre‑cabling enables easy adaptation of the CMMs to future measurement tasks without costly downtime. A range of adaptability options can be flexibly selected during initial CMM configuration or set up later as upgrades.
