Abstract: In an embodiment an optical arrangement includes a multicore fiber having at least a first fiber core configured to guide a first illumination light and a second fiber core configured to guide a second illumination light, wherein the multicore fiber comprises a fiber scanner configured to deflect the multicore fiber or the multicore fiber is followed by a mirror scanner; and a wavelength dispersive beam combiner configured to spatially superimpose the first illumination light and the second illumination light in an object space.

Abstract: An optical probe (2) for optically examining an object (1) is described, said optical probe having a first optical beam path for a scanning imaging method and a second optical beam path for a spectroscopic method. The optical probe comprises a first optical fibre (9) in the first optical beam path and a scanning apparatus (10) that is configured to laterally deflect the first optical fibre (9) or illumination light (31) emerging from the first optical fibre (9) for the purposes of scanning the object (1) during the scanning imaging method. The optical probe comprises a second optical fibre (11) in the second optical beam path, said second optical fibre being configured to guide excitation light or detected object light for the spectroscopic method, and a beam splitter filter (15), wherein the beam path of the scanning imaging method and the beam path of the spectroscopic method are brought into partial overlap in the probe (2) by means of the beam splitter filter (15). The optical probe (2) has a diameter of no more than 5 mm. Furthermore, a method for operating the optical probe (2) is specified.
