Illumination module for angle-selective illumination

Abstract

The invention relates to an optical device comprising an illumination module (100) with a carrier (110) which has, for example, at least one light-permeable region (112). The illumination module (100)comprises a plurality of light sources (111) that are arranged on the carrier (110).

Description

technical field [0001] Various embodiments of the invention relate to laser scanning microscopes and microscopes. In various embodiments, a lighting module for a corresponding optical device comprises a carrier with a plurality of light sources and optionally at least one light-transmitting region. Background technique [0002] Illumination of a sample from different illumination directions (angle-selectable illumination or structured illumination) is known from DE 10 2014 112 242 A1. By combining the images acquired for different illumination directions a result image can be determined, for example with phase contrast. Phase-contrast imaging can thus be achieved by digital post-processing with the aid of angle-selectable illumination. [0003] To some extent it can be difficult to combine appropriate illumination modules for angularly selectable illumination with conventional optical devices such as laser scanning microscopes (LSM) or optical microscopes with objective le...

Problems solved by technology

[0003] To some extent it may be difficult to combine corresponding illumination modules for angularly selectable illumination with conventional optical devices such as laser scanning microscopes (LSM) or optical microscopes with objective lenses

This is possible because there is often only limited construction space in such conventional optical devices
