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.

Product Overview

ImageMaster® PRO 10

MTF testing with outstanding speed and accuracy

ImageMaster® PRO 10

ImageMaster® PRO 10 enables customers to significantally increase their yield. It is the fastest and most accurate MTF measurement system on the market for qualifying mobile phone lenses and other miniature lenses:

  • Measurement accuracy of 0.8 % MTF on-axis and 1.5 % off-axis

  • Measurement time of 1.3 seconds per sample (2700 UPH)

  • Up to 53 measurement points in 27 field positions (cameras)

  • Maximum Field of View 215° (optional)

  • Tele application for small field of view

  • Finite – Finite plane and sphere from 300 mm to infinity

  • Stable chamber temperature (+ / – 2 °C) realized by fans and checked by temperature sensors

  • Measurement traceable to international standards

  • Vibration insulated measurement chamber

  • Cleanroom compatible

ImageMaster® PRO X Compact

MTF industry standard meets compact design

ImageMaster® PRO X Compact

With the ImageMaster® PRO X Compact, we offer our customers the best price-performance ratio. The compact production tester is more precise, faster and more cost-effective than its predecessor.

  • Wafer bow measurement

  • Highest FFL accuracy for spacer thickness determination

  • Tilt correction function (bow compensation)

  • Wafer of any size up to a diameter of 8 inch (200 mm)

  • measurement of lenses on circular or rectangular wafers or single lenses that are arranged in a tray

  • Easy loading due to kinematic mount and wafer rotation and shift adjustment tool

  • An assortment of pass and fail criteria allows use of the most suitable criterion for each type of lens

  • Measurement traceable to international standards

  • Cleanroom compatibility

ImageMaster® PRO SF

MTF testing of short finite distances


The ImageMaster® PRO SF is qualified for applications such as FOD (Finger-on-Display), endoscope optics, swallowable pill cameras or optics for gesture control. The setting of different finite distances makes a flexible and at the same time highly accurate MTF measurement possible.

  • Finite distances of up to < 1 mm (< 1 mm – 40 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 99 measurement points in 50 field positions (virtual cameras)

  • Measurement time of 2.0 seconds per scan (depends on sample)

  • Measuring frequency up to 350lp/mm

  • Wafer variants on request (6“ & 8“ Wafer)

  • Measurement traceable to international standards

  • Cleanroom compatible

Applications ImageMaster® PRO


ImageMaster® PRO products measure the following parameters:

  • MTF on and off axis

  • MTF at best lens performance (tilt correction)

  • Multi frequency MTF measurement

  • Effective Focal Length (EFL)

  • Flange Focal Length (FFL)

  • Field curvature

  • Tilt of image plane

  • Depth of Focus DOF

  • Best focus position

  • Astigmatism

  • Relative distortion



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

  • Polar diagram for displaying MTF symmetry in image field
