Optical testing device MTF

automaticcomputer-controlled

The modulation tranfer function is an objective criteria for the imaging quality of optics. 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. Depending on specimen parameter, there are different setups available. The MTF benches of OEG provide fully automatic characterization of imaging quality on- and off-axis for any azimuth and type of object/image conjugates by measurement of the modulation transfer function (MTF). The operational area covers almost all standard optics for the visible and NIR spectral range. The modulation transfer function (MTF) is a recognized control criterion for the optical imaging quality. It characterizes the resolution of optical systems on the axis and in the image field. Beside the MTF a lot of other parameters can be measured, e.g. the focal length, chromatic aberrations, distortion, astigmatism, field curvature, depth of field. Already since 1991 OEG GmbH works in the field of MTF measurement. The OEG-MTF-benches are working satisfactorily with many german and international considerable optics manufacturers in the production control. In addition it is also outstanding suitable for the employment in teachings, research, laboratory as well as goods in and outgoing inspection.
