TRIOPTICS expands product portfolio in MTF measurement.

TRIOPTICS expands the portfolio of ImageMaster® PRO measurement systems with three new model variants for measurement requirements that result from the latest technology trends for smartphone camera optics.

One new technology in the mobile phone market is under-display camera technology – camera optics are almost invisibly hidden under full-screen display surfaces. High-resolution, professional photography and the zoom capability of cameras are two further key drivers for the future. All three trends cause new challenges for measurement technology. One of the three new measurement systems – ImageMaster® PRO Display for image quality measurement of smartphone displays – will be presented to visitors at Touch Taiwan in Taipei.

“It can be assumed that the under-display camera technology will be used in the future especially in the selfie cameras of smartphones as well as in tablets,” explains Product Manager Stephan Marschner. Measuring the image quality of displays, with a hidden camera under the display, is also new territory for the market leader TRIOPTICS, as this involves precisely determining the influence of the display glass on the image quality. “Due to the MTF measurement, optimized for this application, the ImageMaster® PRO Display performs the precise measurement of the display within one second.”

The ImageMaster® PRO HD is a newly developed device to meet the measurement requirements of new types of high-resolution smartphone optics. With 43 integrated field positions (cameras), the system enables a particularly high measurement point density. “This enables the quality assessment of very complex, high-quality optics such as free-form lenses,” “which is a must for quality assurance in the field of high-resolution photography with mobile phones.” says Stephan Marschner.

A third groundbreaking trend in the mobile phone market is the zoom capability of cameras. Here, TRIOPTICS relies on the ImageMaster® PRO ST for highly precise measurement of the smallest fields of view (FOV) using a new type of single telescope measurement technology. “This MTF tester for smartphone zoom lenses is the only production system on the market that offers a particularly narrow field of view (FOV) at an extremely high measurement point density,” explains Stephan Marschner. “The ImageMaster® PRO ST requires less hardware components, such as cameras, cables or holders, while enabling a very simple setup and adjustment. We have developed a serial product that allows smartphone and lens manufacturers to change products quickly and easily, making it also very attractive economically.”

For years, the ImageMaster® PRO product family has set the global standard for testing the imaging quality of mobile phone camera lenses in mass production. The ImageMaster® PRO devices are the fastest and most precise devices worldwide. With the three new developments of the ImageMaster® PRO series TRIOPTICS underlines its technology leadership also for the production of future mobile phone camera lenses.
