Arrangement, microscope and method for TIRF microscopy

摘要

An arrangement for TIRF microscopy, having an illumination optical unit with an illumination objective for illuminating a specimen on a specimen carrier in a specimen plane via an illumination beam path. An optical axis of the illumination objective includes an illumination angle that differs from zero with the normal of the specimen plane. A detection optical unit with a detection objective in a detection beam path includes a detection angle that differs from zero between an optical axis thereof and the normal of the specimen plane. A transition element between the specimen carrier and both objectives is arranged both in the illumination beam path and in the detection beam path. The transition element corrects aberrations that arise on account of the passage through media with different refractive indices of radiation to be detected and/or radiation for illuminating the specimen.
