The TE42-LL 2AR incorporates two aspect ratios (2AR) into one chart. Both 4:3 and 16:9 aspect ratios are now on one chart plane. The center of the chart will stay exactly the same as the original TE42-LL test chart, but now, extra Siemens stars are added on the outside to account for the different aspect ratios.
Having multiple aspect ratios on one chart plane will provide more flexibility for smaller test labs and also reduce the chances of damage when changing multiple charts.
There are various sampling rates for the chart. Our sales team will be happy to provide you with further information on this.
The TE42-LL 2AR is supported by the iQ-Analyzer-X image evaluation software.
