More Information
Summary:The invention relates to a microscope illumination system comprising at least one laser light source emitting a light beam (1), beam-guiding optical elements for generating an illumination beam path comprising marked planes, such as pupil and field planes, and a homogenising arrangement for forming a light field homogenised in terms of intensity and oriented towards the sample to be observed. According to the invention, the above-mentioned microscope illumination system is provided with a homogenising arrangement wherein optical elements are provided in a plurality of successive sections (4, 5, 6) of the illumination beam path. Said optical elements reduce the coherence of the laser light, homogenise the intensity of the light beam (1) in a pupil plane (2) of the illumination beam path, and homogenise the intensity of the light beam (1) in a field plane (3) of the illumination beam path. An optical system for imaging the homogenised light beam (1) on the sample is arranged downstream of the homogenising arrangement.
