Industrial measurement equipment

Confocal 3D-measurement system

The 3D-Scanning-System enables non-contact measurement of object geometries in nearly real-time. The system is the result of a collaborative effort between POG and the University of Ulm‘s Institute for Laser Technology in Medicine and Measurement Technique (www.ilm-ulm.de).
A typical application is the exact measurement of tooth geometries in dentistry and orthodontics. High measurement speed, very large aspect ratio and easy handling (the scanner is simply waved over the object) make the scanner an excellent tool for a wide range of 3D measurement applications.
Its flexible design allows for customization of the system to your specific scanning & form-factor needs. Please contact us to learn more about a customized solution.

Further applications include:

Inline quality control
- component or tooling inspection (geometry, deterioration, angular tolerances)
- PCB inspection (correct placement of elements)
- welding inspection (defect analysis)
- spatially resolved measurement of film thickness
Reverse Engineering
- conversion of object geometries into CAD models (scanning of free form surfaces and undercuts)

Specifications of a typical configuration:

Accuracy	25 µm in x-y 5 µm in z
Speed	1-5 ms single-shot-measurement with max. resolution in z 35 cm2/s at max. resolution in x,y,z
Measurement Field	11x11x11 mm3 for single shot measurement Extended by moving the scanner or the object
Working Distance	Typ. 50 mm
Light source	LED, Xenon Lamp

Wide Field Collimator

This system was developed specifically for inline inspection of mobile phone cameras. It can be integrated into production lines and may also be used in stand-alone test setups. This new system is perfect for testing distortion, resolution and focus for a variety of different objective lenses with a focal length around 4 mm.

The collimator is adjusted to infinity and covers an object field of 68°. A special chessboard pattern is used for the standard reticle. Upon customer request it can be adjusted on demand to match the parameters to be checked.

An adjustable white light LED-illumination with 12...24V DC is integrated by default.

The system is available from stock in small quantities and can be modified to meet your specific demands.

Solar simulation system

This solar simulation system is a part of an aerospace simulation equipment. It can be used for simulation of radiation at spectral range between 0,2 and 2,5 micrometer. At testing plane the intensity of radiation can be adjusted from 0,5 bis 1,4kW/m². Main components are 7 xenon lamps, lens arrays consisting of 37 hexagonally edged single lenses and an Off-Axis parabolic mirror made of 127 single mirrors.
