Arrangement for illumination and/or detection in a microscope

1. A laser scanning microscope comprising:

a dispersion element operable to spatially disperse an object light coming from an object under study;

at least one selectively switchable micro-mirror arrangement in a detection beam path which is used for the wavelength selection of the spatially dispersed object light wherein the selected wavelengths that have been spatially dispersed by the dispersion element impinge upon a detector as dispersed light

wherein the at least one selectivley switchable micro-mirror arrangement comprises a plurality of individually controllable switching mirrors and each one of the plurality of individually controllable switching mirrors are controlled so that the individual spectral components of the specimen radiation are reflected onto the detector sequentially for reception of the entire spectrum.

2. An arrangement according to claim 1 wherein the dispersion element includes at least one of a grating and prism.

3. An optical connection of an arrangement according to claim 1 , the detection beam path comprising dichroic beam splitters for splitting the detection beam path into individual channels.

4. The arrangement according to claim 3 , wherein the optical connection is carried out via light-conducting fibers.

5. The laser scanning microscope according to claim 1 , further comprising a detector pinhole positioned at a conjugate plane to an object plane and operable to provide the object light to the dispersion element.

6. The laser scanning microscope according to claim 5 wherein the dispersion element receives an uncollimated object light from the detector pinhole.

7. A microscope arrangement with a switchable mirror array comprising:

a detector pinhole operable to receive a detection beam coming from a sample under study;

a dispersion element operable to spatially disperse the detection beam;

a switchable mirror arrangement operable to switch selected wavelengths of the spatially dispersed detection beam;

a focusing element operable to focus the selected wavelengths; and

a detector operable to receive as dispersed light the focused wavelengths that have been selected by the switchable mirror arrangement and spatially dispersed by the dispersion elements,

wherein the switchable micro-mirror arrangement comprises a plurality of individually controllable switching mirrors and each one of the plurality of individually controllable switching mirrors are controlled so that the individual spectral components of the specimen radiation are reflected onto the detector sequentially for reception of the entire spectrum.

8. The microscope arrangement according to claim 7 wherein the pinhole includes a second switchable mirror arrangement operable to adjust the size of the entrance aperture.

9. The microscope arrangement according to claim 7 , wherein the detector pinhole is positioned at a conjugate plane to an object plane.

10. The microscope arrangement according to claim 9 , wherein the dispersion element receives an uncollimated detection beam from the detector pinhole.
