MTF system for image quality measurement of lenses and camera systems ImageMaster® HR

08 Oct 2015

The ImageMaster^® HR is a fully equipped quality test station for medium sized sample lenses. Its modular and upgradeable design enables the measurement of the image quality (MTF) and a wide range of other optical parameters for today and future needs. The instrument is used in the R&D laboratory as well as in the quality assurance or in production. The unique vertical setup of the ImageMaster^® HR is space saving and ensures the most convenient and accurate positioning of the sample lens mounts.

With the collimator on the precise swinging arm an ultra-wide field angle of ± 105° can be measured for infinity conjugate samples. An upgrade for finite testing can easily be adapted to the system with an additional motorized stage and object generator.

For the whole product only high quality components are used to ensure the most accurate measurements for MTF testing on the market.

Software

TRIOPTICS has developed a new forward-looking software package called MTF-Lab. The advantages of MTF-Lab are:

Functions for easier alignment of the sample under test
Intuitive user interface and time saving lens test routines
Customizable test configuration set-ups with improved script language for individual test routines
The test results are available in a variety of file formats. The certificate will be created in HTML format.
MWIR and LWIR will be supported employing the innovative area sensor method
