Large Area Scan Macroscope

Innovative development in glaciology for the investigation of the microstructure of polar ice cores

The large area scan macroscope from Schäfter+Kirchhoff was developed for the Alfred Wegener Institute for Polar and Maritime Research in Bremerhaven for use at temperatures down to -30°C (and ultimately -60°C).

This ice scanner is a vast improvement over traditional methods in terms of quality, reproducibility and speed.

Laser diffraction system

For measurements of diameters, geometries and edge detection with high precision and speed.

• Evaluation of shadow edges
• Evaluation of Fresnel diffraction patterns

CCD line scan cameras with integrated bright field illumination

High-contrast image acquisition of structured objects; making the invisible visible. Illumination and image acquisition techniques that are well adapted to the object properties emphasize the object features of interest. Elaborate image processing algorithms are avoided.

Line scan sensor heads by Schäfter+Kirchhoff combine the line scan camera, the measuring object and a LED-based directed bright field illumination in a ruggedized unit, highly suited for industrial applications. The LED illumination is aligned with the camera lens and has a long service life of several years.

Large area scan microscope

Large area scan microscope for automated grid finger inspection.

This 2D-scanner with its modular conception and the normalized interfaces is well suited for camera and scanner carridge, as well as for the quality control in the lab and in productional environments. With only little efford the conversion from b/w to color camera or changing the illumination device is accomplished

O-Ring Groove Surface Analysis: Inspection of sealing areas

Inspections system with three CCD line scan cameras - endocentric and Scheimpflug optical configuration

The imaging system developed by Schäfter+Kirchhoff for inspecting the base and sides of a machined groove, for the acceptance of an O-ring, uses three CCD line scan cameras, SK512ZPD. Two cameras are positioned to utilize the Scheimpflug principle for monitoring the internal sides of the groove. A third camera monitors the base of the groove and its surrounding surface details.

This particular configuration allows complicated surface features to be resolved at signal intensities with 60-times higher amplitude and at 3-times better resolution, when compared with a conventional system.

Fünf auf einen Streich

Fünf Zeilenkameras erfassen synchron Bild- und Messdaten. Eine überlagerte strukturierte Laserbeleuchtung erweitert die zweidimensionale Messung um eine weitere Dimension (z.B. Tiefe, Schwingung, Durchbiegung).

Das Messsystem ist modular aufgebaut; mit identischem Gehäuse und identischer Schnittstelle stehen Zeilenkameras mit 512–5150 Pixeln zur Verfügung.

Laser Light Section

No-contact geometry and contour control

Light section methods are utilized as a 3D measurement technique for more than 70 years as a no-contact geometry and contour control. Modern key components for laser light sectioning are the laser line generators 13LT… and 13LR…

Application: 3D contour control of a safety key profiles

Laser Micro Line Generator 13LR…

A key component for the 3D laser measurement technique

The 13LR… laser line generator was specially developed for the 3D profile measurement using the laser light-sectioning method. Its specific characteristics are the homogenious intensity distribution, and the constant line width throughout the whole measuring area.

Application: profile measurements and gage exactness of rail tracks
