ImageMaster® Universal - MTF Testing in the Spectral Range UV-VIS-NIR-SWIR-MWIR-LWIR
The ImageMaster® Universal Series has been specifically developed to cover the MTF measurement of a large set of optical parameters over a wide spectral range. Virtually any existing lens system ranging from high performance photographic imaging lenses to high resolution telescopes can be accurately measured in: IR, Visible, UV.
ImageMaster® Universal – a flexible system for MTF measurements
Key Features:
- Image quality evaluation of any existing lens system: infinite, finite, afocal
- Measurement of the modulation transfer function (MTF) off-axis and on axis
- Modular and upgradable design
- Quick exchange of different modules within a few minutes (e.g. changing from VIS to IR)
- MTF values tracable to international standards
- Perfectly aligned measurement heads using proprietary alignment procedures
- Cover for diffraction limited collimators to avoid ambient light and air turbulences
- Innovative and time saving IR area sensor method
- Years of experiences and from a high diversity of customers
Applications:
- Modulation transfer function on axis and off axis
- Through Focus MTF
- Line Spread Function
- Phase Transfer Function
- Effective Focal Length
- FFL/BFL (relative)
- Distortion
- Astigmatism
- Field Curvature
- etc.
Different setups depending on customer requirements
MTF-Lab Software for ImageMaster® Universal
TRIOPTICS has developed a new forward-looking software package.
One main feature is the support of UV or IR detectors employing the scanning aperture method. Several useful functions are integrated which help the user in scanning and perceiving the correct image position of the sample under test. Changing the measurement mode is now easier and time-saving. All important measurements for the imaging properties have been revised and are quickly accessible.

Key Features:
- Striking new and easy to handle graphical user interface makes the most important functions only one mouse-click away
- Customizable arrangement of graph windows
- Script tools to create automated user defined measurements including high-level programming functions such as stage controlling, data manipulation, loops and variables
- Data export to a variety of file formats
- Logging of successive measurements
- Making up certificates using the hypertext language protocol (HTML)
All these features make the ImageMaster® MTF-Lab software package the preferred choice for R&D and laboratory work. The software is designed to work under Microsoft Windows 7 operating system.
