OEG GmbH was founded in 1991 and works since that time in the field of MTF testing. Based on that long experience OEG GmbH provides a comprehensive product line for the computer-controlled fully automatic measurement of the modulation transfer function (MTF) for quality assurance in the optics manufacturing and research. Depending on specimen parameter, there are different setups available. MTF, Effective Focal Length (EFL), Back Focal Length (BFL), Flange Focal Length (FFL), Distortion, Field Curvature, Chromatic Aberrations (axial, lateral), Astigmatism, Depth of focus, Rotation Symmetry...

the control auf an automatic measuring sequence is at least of equal importance like the MTF calculation algorithms. Additionally, the optical components of the MTF test bench and the mechanical components must meet high quality demands. MTF test benches from OEG guarantee the compliance with the demands of a high accurate MTF measurement!  •  ully automatic, software controlled f measuring sequence for up to 7 automatic axes;  •  lternatively manual or automatic a azimuth-dependent measurement  • automatic, software controlled symmetry measurement;  •  peration and control of the hardware...

The increase of camera technology in devices like webcams, automotive applications like driver assistance systems and cell phones has created a need for real time optical test equipment that is capable of qualifying the alignment and focus of a lens to a camera in a very short time. This requirement necessarily means that all relevant field points within the image must be presented to the unit under test simultaneously. An innovative Approach OEG has developed the MTF-PENTATEST prod uct line to meet the new needs in optics and sensor manufacture. MTF-PENTATEST offers a complete new approach...

Optics Test Stations for single lenses and optical systems The Optics Test Stations are an indispensable tool for control of incoming goods and quality assurance in optics production! OTS 200 and OTS 500 featuring the objective, motorized and software controlled measurement of optical parameters of single lenses and optical systems like: • Effective Focal Length (EFL), positive and negative • Back Focal Length (BFL) • Radius of Curvature (R), positive and negative • Flange Focal Length (FFL) • Modulation Transfer function (MTF), on axis, tangential and sagittal • Centering error • Lens...

FLATSCAN is an optical, noncontact surface profilometer. It was specially developed for large specimen sizes. FLATSCAN features the measurement of 2D and 3D surface form, radius of curvature and slope. An additional software module provides the calculation of thin film stress (wafer stress) for applications in semiconductor technology. The basic principle is based on deflectometry. Therefore the FLATSCAN for all kind of polished surfaces like wafers, mirrors and polished glass. One of the essential features of the FLATSCAN is the large radius-(slope-) measuring range. Therefore the...

CROSSDETECT – Windows image processing software for autocollimators and collimating telescopes CROSSDETECT is an image processing software, which was specially developed for use in connection with autocollimators. CROSSDETECT is suited perfectly for all applications, where autocollimators can be used, like:  •  easurement of small angles M  •  ltra precision angular adjustment and U calibration  •  edge- and prism angle measurement W  • A ngle position monitoring The software can be used either for the upgrade of visual autocollimators with an objectively, electronic data acquisition or the...

Wedge Angle Measuring System The wedge angle measuring system serves specially for the measurement of the wedge angle or parallelism of optical windows, filters and glass plates.  • nterface to other devices or software applications I  •  ast and easy measurement of small angles F with high accuracy It works in double transmission with a reference mirror, which is placed under the specimen table. The acquisition of measuring values is performed by an autocollimator, equipped with CCD-camera and the image processing software CROSSDETECT.  •  everal special measuring functions S  •  asy...
