Abstract

A lighting device (50) is provided for an optical observation device (2, 2'). The lighting device (50) is equipped with - at least one illumination beam path leading from an illumination light source (41) to an observation object (3) for generating a luminous field (57) on the observation object (3) using illumination light, and - a projection device (5, 53, 70) for projecting a structure onto the observation object (3). The projection device (5, 53, 70) acts on the illumination light in such a way that the projection of the structure onto the observation object (3) takes place within the illumination field (57) using the illumination light generating the illumination field (57). Furthermore, a method for identifying an object area of ​​an observation object (3) imaged on an image sensor (23, 61, 61A, 61B) of an optical observation device (2, 2') is provided. In the method, a structure is projected onto the observation object (3) using illumination light, which generates a luminous field (57) on the observation object (3). This structure serves as an indicator for the object area of ​​the observation object (3) imaged on the image sensor (61).
