The individual test areas in an interactive overview
detail contrast objects
The precisely manufactured 8 detail contrast objects in the Primus A allow for an easy verification of the representation of low contrasts
dynamic levels
The 17 dynamic levels with integrated low contrast are numbered for quicker and easier orientation.
Resolution test
The line size resolution test allows for a visual determination from 0.5 mm LP/mm to 5 LP/mm
The test device has a surrounding grip for simplified handling
