Abstract

A microscope objective for imaging a specimen using a microscope, the microscope objective being designed as an air objective for microscopy without an immersion medium or as an oil immersion objective for microscopy with an oil-based immersion medium or as a water immersion objective for microscopy with a water-based immersion medium. The front lens of the microscope objective is provided with a coating which repels an immersion medium and is lipophobic and hydrophobic if the objective is an air objective, only lipophobic if the objective is a water immersion objective, and only hydrophobic if the objective is an oil immersion objective.
