Abstract
A mirror optic (10), particularly for near-field optical measurement of a specimen (1) is described, which mirror optic (10) has a reflector (11) with the shape of a paraboloid with a paraboloid axis (12) and a focal point (13), which can be illuminated along a first illumination beam path (I), whereby the reflector 11 has at least one edge recess (14) in such a way that the focal point (13) can be illuminated along a second illumination beam path (II) which deviates from the first illumination beam path (I). A near-field microscope with such a mirror optic is also described.
Claims19
A mirror optic adapted for near-field optical measurement of a specimen, including:
- a reflector in the form of a paraboloid with a paraboloid axis and a focal point, which may be illuminated along a first illumination beam path, wherein
- the reflector has at least one edge recess, so that the focal point can be illuminated along a second illumination beam path which deviates from the first illumination beam path.
