ImageMaster® PRO 5 Compact - Efficient and Flexible MTF Test Station Optimized for Production in Cleanrooms (1000/ ISO 6)
The ImageMaster® PRO 5 Compact is a production MTF tester for qualifying mobile phone and other miniature lenses measuring objective lenses with an effective focal length between 1 and 12 mm.
The instrument is cost optimized for throughput, compactness and durability, with a typical measurement time of 3 seconds.
Key Features:
- Ergonomically designed space-saving table top instrument optimized for cleanroom operation
- Measurement time less than 2.5 sec/lens for tray system or 5.0 sec/lens with all through focus curves
- MTF on 17 field positions (sag + tan)
- Based on ImageMaster® PRO 5 measurement technology
- Digital camera technology
- Adjustable field angles up to FOV 120 deg
- Automatic X/Y tray system (150×150 mm²)
- Automatic X/Y alignment
- Up to 100 samples per tray
- Multi-sample tray system for high volume testing
- Measurement results traceable to international standards
- Reinraumklasse 1000/ ISO 6
Applications
ImageMaster® PRO 9 for ultra-fast MTF testing, measures the following parameters:
- MTF on-axis
- MTF off-axis
- Through focus curves
- Effective focal length
- Flange focal length
- Depth of focus
- Tilt of image plane
- Azimuth of image plane
- Field curvature
- Astigmatism
- Relative optical distortion
Software for Automated Image Quality Testing
The software for the MTF tester is specially designed for the use in a production line environment.
ImageMaster® PRO provides a stable platform and overwhelming number of features. Software uses proven algorithms for calculation of the MTF, automatic correction for spatial frequencies in off- axis positions taking into account of the sample distortion, noise reduction and provides reliable and ultra-accurate measurement results.
Advantages
- Automatic pass or fail results based on a multitude of freely selectable criteria
- Software enabling real- time images of all cameras.
- Individual setting of spatial frequencies for each camera
- Settings to enable focusing curve for on-axis and/or off-axis cameras
- Three security levels, set up files and critical functions are password protected
- Storage of lens and batch data, data analysis over Excel
- Graphical intuitive representation of the measurement data in order to detect lenses out of specification at an early stage
- Polar diagram for displaying MTF symmetry in image field
