Abstract
A measuring device includes a light source that emits light of a plurality of wavelengths, in particular a continuous spectrum, a first confocal diaphragm, through which light from the light source passes, and an optical illuminating/imaging system having a first splitting optical element designed as a prism or grating. The optical illuminating/imaging system, which is designed such that the light enters the first splitting optical element collimated, includes a first lens system having at least one first lens that is spatially separated from the first splitting optical element, the effective focal length of the first lens system being significantly different for different wavelengths, and the optical illuminating/imaging system being designed such that focus points of different wavelengths are formed at different locations along a line segment. The measuring device is configured to measure an object that intersects with the line segment and reflects at least a part of the light.
