ImageMaster® Cine Linear - MTF Testing Service and Adjustment of Cine Objective Lenses
The ImageMaster® Cine Linear is especially recommended for incoming quality control. It performs on-axis measurements and is used for FFL measurements as well.
Key Features:
- Horizontal measurement setup
- FFL measurements
- On-Axis Finite Measurement
- On-Axis MTF Infinite with two different collimators
- Two collimators in holder for quick change of EFL
- Different filters and reticles
- Modulable LED (RGBW) light source
- Option: Optical low pass filter
- Finite movement: 200 – 3,048 mm
Applications
The ImageMaster® Cine Linear measures various parameters, e.g.:
- MTF on axis
- Effective Focal Length (EFL)
- Flange Focal Length (FFL)
- Focal shift
- Chromatic aberration
- Object distances (image to object)
- Zoom shift
