Optical Measurement

Uncompromising Quality Assurance, Increase of Productivity & Cost Savings

Optical 3D measurement is a great opportunity for the manufacturing industries to maintain the quality inspection in all stages of their part production and optimization. The non-contact 3D scanner is based on blue light structured scanning, delivering precision scans at short time, ideally for the deviation analysis to CAD models.

Thus, the technology allows industries to raise their quality with shorter product cycles and quick lead times.

GOM ATOS is an optical 3D coordinate measurement system having high-tech software and hardware for repeatable measurements, providing desirable accuracy and flexibility.

Merz As Your Optical Measurement Service Provider

Non-destructive testing

The dimension analysis can be conducted in short time to the CAD models and with precise scan quality.

Fast evaluation

In comparison to conventional measuring methods, optical measurement delivers part evaluation results faster and more efficient.

Measurement reports and protocols
We provide measurement reports and protocols after the scanning process as of customer requirements

All part sizes

Regardless of the component size and shape, through optical measurement, we can deliver precise measurement results

Scanning Process

 

Optical Measurement Principle

During the scanning process, stripe patterns (Zebra-pattern) with two different colors are projected onto the object surface and captured by two stereo cameras. Cameras and projector enable the calculation of 3D coordinate points from three different ray intersections. Since the beam paths of both cameras and the projector are known in advance through calibration, 3D coordinate points can be calculated from the three different beam sections.

Nominal/Actual Comparison Against Data Record

Vectorial representations with highlights

Evaluation of features and links

Form and position Analysis

We offer the actual-nominal comparison as a false color representation and generate the basic sampling of analysis on

STL data

The CAD file derived from STL data can be aligned according

to the drawing and the coordinate system with determining the dimensions

Target-performance comparison with deviation indicators by

section analysis

ATOS solution speeds up of all production phases and beneficial in many industries for the inspection of parts such as injection molding, die-casting, sheet metal, tools and dies, prototypes, blow molding, thermoforming and all freeform surfaces.

 

GOM ATOS​

GOM ATOS (Advanced Topometric Sensor) measures components fast and in high resolution to ensure a dependable nominal/actual comparison.

This industrial non-contact 3D scanner provides precise

scans and detailed resolution. With the ATOS optical 3D scanner, it is simple to capture all complex parts and shapes in 3D visualization. As a result, STL data can be generated from the 3D models.

GOM ATOS Benefits

Blue Light Technology 

The narrow-band blue light filters out the interfering ambient light during the application, securing high-quality outcomes and eliminating disruptive factors. 

Assured Measuring Data Quality

Environmental changes as well as part movements are constantly monitored by the ATOS sensors, securing steady accuracy, and measuring quality. Surface reconstruction, part reconstruction, tool correction and Reverse Engineering, dimensional analysis and the entire inspection process of the part can be observed and conducted through GOM Inspect, ZEISS Calypso and Holos.

Expandable Measuring Fields

Due to interchangeable lenses, flexibility to provide small to larger measuring field views with detailed accuracy is ensured.
