Optical arrangement with an overview function for a catadioptric microscope objective

An optical arrangement, comprising:

• a center axis;
• an object side;
• an image side;
• a catadioptric arrangement;
• the catadioptric arrangement comprising a first, partly reflective optical component and a second, partly reflective optical component, which are arranged in succession in the beam path along the center axis such that the first optical component is arranged on the image side of the second optical component;
• the first optical component comprising a radially inner region and a radially outer region in relation to the center axis, the inner region being configured to be at least partly transparent to light incident from the object side, and the outer region being configured to reflect light incident from the object side;
• the second optical component comprising a radially inner region and a radially outer region in relation to the center axis, the outer region being configured to be transparent to light incident from the object side, and the inner region being configured to be at least partly transparent to light incident from the object side and to reflect light incident from the image side;
• and
• at least one further optical component with positive refractive power being arranged at the inner region of the second optical component on the object side.
