1. An arrangement for coupling laser radiation, into a scanning head of a laser scanning microscope, the scanning head having a scanning unit scanning in at least two dimensions, comprising:
- a microscope objective for focusing the radiation on an object;
at least one light-conducting fiber coupled with the scanning head, the radiation being focused on the object via said at least one light-conducting fiber; and
an AOTF arranged between a UV laser and a light-guide input of said at least one light-conducting fiber.

Abstract
An arrangement and corresponding method are provided for coupling radiation, preferably laser radiation, into a scanning head with a scanning unit in at least two dimensions. The radiation is focussed on an object via a microscope objective via at least one light-conducting fiber which is coupled with the scanning head. A collimator is arranged downstream of the fiber end at the scanning head for collimating the radiation exiting in a divergent manner at the fiber end.

3. A method of coupling radiation in a laser scanning microscope, the method comprising:
-
inputting a UV laser radiation from a laser source into an optical fiber wherein the inputted laser radiation is scanned by a scanning head having a scanning unit that can scan in at least two dimensions;
focusing the scanning laser radiation on an object through a microscope objective; and
wherein the laser radiation is directed to the optical fiber or is directed past the optical fiber by controlling an AOTF coupled between the optical fiber and the laser source.
