ImageMaster® HR UltraPrecision – Image Quality Test Station
For ultra-precise measurement of MTF and other optical parameters TRIOPTICS has developed the new ImageMaster® HR UP. It completes the proven ImageMaster® HR product line – the preferred MTF Test Station worldwide. A high-precision air bearing sample holder leads to an increased mechanical stability of the ImageMaster® HR UP. Therefore, an enhanced measurement reproducibility is achieved.
Key Features:
- Accuracy traceable to international standards
- Fully or semi-automated, ultra-accurate, multifunctional MTF test station
- R&D MTF test station for medium sized samples
- MTF measurement at finite and infinite conjugates
- Instrument available for NUV / VIS / NIR
- Vertical set up for most convenient and easy lens positioning
- Optimal design prevents vignetting
Applications:
The ImageMaster® HR UltraPrecision measures the following Parameters:
- MTF in infinity conjugate configuration
- MTF on-axis and off-axis (angle up to ± 70°)
- Effective Focal Length (EFL)
- Flange Focal Length (FFL) relative
- Distortion
- Astigmatism
- Field curvature
- Chromatic aberrations
- Chief Ray Angle
