ImageMaster PRO 9
MTF testing in mass production of mobile phone lenses
ImageMaster® PRO
Image quality and MTF tester for large series production
The ImageMaster® PRO series is the leading range of MTF (Modulation Transfer Function) measuring instruments for testing the image quality of mini camera lenses. The mini lenses are used in smartphones, automotive applications, tablets, laptops and action cams. Known for their high accuracy and measurement speed, our MTF tester set industry-wide standards. ImageMaster® PRO instruments are considered to be the most successful MTF measuring systems in the production of single lenses and wafer-based objectives. The calibration of the devices is directly traceable to international standards.
Speed
With a measuring speed of 1.3 seconds per sample, the ImageMaster® PRO 10 sets the standards in MTF measurement and increases your return on investment.
Accuracy
The MTF measurement accuracy of 1.5 % is worldwide top and traceable to international standards.
Reliability
Reliable measuring instruments are indispensable, especially in mass production. The ImageMaster® PRO 10 with its sophisticated hardware and software impresses with its performance.

Up to 50 testing points in one measurement (depending on sample)
Measuring time 2.0 seconds (depending on sample)
Measuring frequency up to 350lp/mm
Measurement traceable to international standards
Applications
ImageMaster® PRO products measure the following parameters:
MTF on and off axis
