Abstract
A detection optical unit () of an optical apparatus is configured to produce an imaged representation () of a sample object () on a detector (). An adjustable filter element () is arranged in a beam path of the detection optical unit () that defines the imaged representation (). A controller is configured to drive the adjustable filter element () to filter the spectrum of the beam path with a first filter pattern (-) and with a second filter pattern (-) and to drive the detector () to capture a first image, associated with the first filter pattern (-), and to capture a second image, which is associated with the second filter pattern (-). The controller is furthermore configured to determine a focus position () of the sample object () based on the first image and the second image. The first filter element (-) here defines a first line and the second filter element (-) defines a second line.
