Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A microscope, comprising:
a pulsed light emitting laser light source with a pulse duration of ≤1000 fs, the pulsed light emitting laser light source being configured to provide an incident light beam; and
an apparatus for reducing a chromatic spread angle of light diffracted at an acousto-optic element, the apparatus comprising:
the acousto-optic element which is disposed in a beam path of the incident light beam and is configured to generate the diffracted light from the incident light beam such that the diffracted light emanates from a virtual interaction point of the acousto-optic element; and
a first and a second focusing optical unit, the first focusing optical unit being disposed in the beam path upstream of the acousto-optic element and the second focusing optical unit being disposed in the diffracted light such that a focus of the incident light beam is situated downstream of the first focusing optical unit in the acousto-optic element and the virtual interaction point is located in a front focus of the second focusing optical unit.
