ImageMaster® PRO 10 - MTF Testing with Outstanding Speed and Performance
As a result of various improvements the 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. Besides the new software architecture and functions, the more precise mechanical components lead to best performance in accuracy, reliability and measurement speed. Faster MTF algorithms reduce the test cycle time so that an outstanding throughput is achieved.
The ImageMaster® PRO 10 features a 15% increased productivity compared to the ImageMaster® PRO 9.
The new ImageMaster® PRO 10 also provides additional measurement functions. For example, measurements at different frequencies and RGB measurements can be performed to determine chromatic aberration. An upgrade of four additional cameras allows the measurement of relative illumination for testing the homogeneous illumination of lenses in the field.
The exceptional innovations make this MTF production tester ready for future needs and upcoming high resolution megapixel lenses.
