Abstract
A digital pathology imaging apparatus includes a single line scan camera sensor optically coupled with first and second optical paths. In a first embodiment, transmission mode illumination and oblique mode illumination are simultaneously used during a single stage movement that captures a low resolution macro image of the entire sample area and the entire label area of the slide via the first optical path. In a second embodiment, transmission mode illumination is used during a first stage movement that captures a low resolution macro image of at least the entire sample area via the first optical path and oblique mode illumination is used during a second stage movement that captures a low resolution macro image of at least the entire label area via the first optical path.
