Abstract
A description is given of an illuminating device for a microscope (,), having a light source (,), an illuminating optical system (,) and an LCD (,) arranged in the illuminating beam path (,). The illuminating light is directed onto the object (,) from the light source (,) via the LCD (,), a transparent/opaque pattern being generated on the LCD (,) by means of a control and calculating device (,). The LCD (,) is arranged in a plane (AP′) which is conjugate with respect to the field diaphragm plane or aperture diaphragm plane (AP) and 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. The control and calculating device (,) is constructed as a computer with a graphics card. The graphics card generates the image signal for driving the LCD (,), it being possible for the image generated on the LCD (,) to be represented simultaneously on a separate monitor (,).
