Lighting device for a microscope

Illuminating device for a microscope comprising:

• a light source;
• an illuminating optical system;
• a digital mirror device (DMD) arranged in an illuminating beam path;
• wherein illuminating light is directed from the light source via the DMD onto an object;
• and
• a controller for driving the DMD, wherein a transparent/opaque pattern is generated on the DMD, wherein the DMD is arranged in the plane (AP′) which is conjugate with respect to a field diaphragm plane or aperture diaphragm plane (AP), wherein the DMD has a planar matrix composed of individual pixels arranged next to one another and of the same dimensions, the pixels each being constructed such that they can be driven individually to generate an arbitrary transparent/opaque pattern, wherein the controller is a computer with a graphic card, wherein the graphic card generates an image signal for driving the DMD, and wherein an image generated on the DMD is represented simultaneously on a separate monitor.

Illuminating device for a microscope comprising:

• a light source;
• an illuminating optical system;
• a polymer material responsive to electrical or magnetic signals arranged in an illuminating beam path, wherein illuminating light is directed from the light source via the polymer material onto an object;
• and
• a controller for driving the polymer material, wherein a transparent/opaque pattern is generated on the polymer material, wherein the polymer material is arranged in the plane (AP′) which is conjugate with respect to a field diaphragm plane or aperture diaphragm plane (AP), wherein the polymer material is constructed such that the polymer material can be (AP), wherein the polymer material is constructed such that the polymer material can be driven to generate an arbitrary transparent/opaque pattern, wherein the controller is a computer with a graphic card, and the graphic card generates an image signal for driving the polymer material, and wherein an image generated on the polymer material is represented simultaneously on a separate monitor.
