Abstract
An arrangement for microscopy, having an illumination optical unit with an illumination objective for illuminating a specimen on a specimen carrier. An optical axis of the illumination objective lies in a plane which includes an illumination angle that differs from zero with the normal of a specimen plane and the illumination is implemented in the plane. A detection optical unit with a detection objective is located in a detection beam path. The optical axis of the detection objective includes a detection angle that differs from zero with the normal of the specimen plane. The illumination objective and/or the detection objective has an illumination correction element. A meniscus lens is located between the specimen carrier and the illumination and detection objectives being arranged both in the illumination beam path and in the detection beam path.
