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.

ImageMaster® FingerPrint
MTF testing of smallest finite distances

The ImageMaster® FingerPrint allows you to test the smallest possible finite distances, such as FOD (Finger-on-Display). The setting of different finite distances makes a flexible and at the same time highly accurate MTF measurement possible.
Final distances of up to < 1 mm (< 1 mm – 20 mm)
Setting of the finite distance with < 5 µm accuracy and < 1 µm resolution
Large field of view (up to 140° FOV possible after individual clarification)
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

Software
MTF-PRO
The software for MTF testing in production
The recognized ImageMaster® PRO software, called MTF-PRO, features increased speed, advanced performance and clearly displayed test results. The optimized MTF algorithms are the result of the continuous improvement and TRIOPTICS´ years of experience in the field of MTF measurement.
Automatic pass or fail results based on a multitude of freely selectable criteria
Software enabling real-time images of all cameras
optional with reticle changer (RC), filter changer (FC) or with reticle and filter changer (RC/FC)
Individual setting of spatial frequencies for each camera
Settings to enable focusing curve for on-axis and/or off-axis cameras
Three security levels: setup files and critical functions are password protected
Storage of lens and batch data, data analysis via Excel
Intuitive graphical representation of the measurement data in order to detect lenses out of specification at an early stage
