The Zeiss Star Image Quality Indicator (IQI) that was used as a reference for different resolutions at different pixel sizes. The Zeiss Star is made of 8 different gratings that each span from 32 to 4 μm, (a) shows the IQI on a Nikon XT H with a pixel size of 50 μm, and (b) shows the square in (a) on a Zeiss 520 Versa with a pixel size of 2 μm. The square in (a) shows the region that is seen in (b), demonstrating the significant drop in resolution.
