Problems solved by technology

Especially in cases where large angles are used between different optical paths, a common optical system can be cost prohibitive
If the optics were not used at all, this could lead to an uncontrolled orientation of the sample area; additionally, the light efficiency in the sample area would be limited

Abstract

A lighting module (101) for an optical device comprises a light source unit (102) designed to emit light along one of a plurality of beam paths (112). The lighting model (101) also comprises a plurality of laterally offset optical elements (201-203), each optical element (201-203) of the plurality of optical elements (201-203) being designed to transform at least one respective beam path (112) from the plurality of optical elements.

Description

technical field [0001] Various embodiments of the invention generally relate to a lighting module for an optical device. The lighting module can be provided, for example, for selectable angular lighting from different lighting directions. According to various examples, the lighting module comprises, in particular, a plurality of optical elements which are each provided for varying at least one corresponding beam path. Background technique [0002] Known from DE 10 2014 112 242 A1 are techniques for illuminating a sample from different illumination directions (angle-selectable illumination or structured illumination or angularly resolved illumination). By combining the images acquired for different illumination directions, a resulting image can be determined, for example with phase contrast. Phase-contrast imaging is thus possible by means of digital post-processing with selectable angles of illumination. [0003] A technique involving angle-resolved illumination is also...
