ImageMaster® Cine Flex - MTF Testing Service and Adjustment of Cine Objective Lenses
The ImageMaster® Cine Flex is the perfect choice, when a very flexible system is needed. The user benefits from a quick change between different sample sizes. Measurements with the ImageMaster® Cine Flex can be performed on-axis and off-axis. The simultaneous measurement of two off-axis positions with live MTF values allows for quick adjustment of lens elements to optimize the lenses optical performance.
Key Features:
- Very flexible system
- Adjustment for different sample heights with motorized stage to move the entrance pupil of the sample in measurement position
- Measurement with sample rotation (manually or motorized)
- Performance check on multiple field positions: 2 to 3 motorized telescopes adjusted to infinity – MTF at infinity conjugate
- Off-axis angles up to 52.5°
- Horizontal and vertical measurement set up: allows identification of loose lenses
- Software with Lens repair function
Applications

- MTF on and off axis
- Effective Focal Length (EFL)
- Flange Focal Length (FFL)
- Field curvature
- Tilt of image plane
- Depth of Focus (DOF)
- Astigmatism
- Focal shift
