Assembly for illuminating objects with light of different wavelengths
First Claim
1. Arrangement for illuminating objects with light of different wavelengths in microscopes, automatic microscopes, and equipment for fluorescent microscopy applications comprising LED light sources for object illumination that are arranged in the illumination radiation path of the microscope or equipment, further comprising a receiving apparatus that is rotatable about an axis of rotation is provided with mounts for each of at least one LED, whereby said receiving apparatus is arranged in a housing that can be attached to an equipment housing or that is positioned in said equipment housing;
- and in that a drive device for defined adjustment of said receiving apparatus is provided such that said LED can be positioned upstream of a light emission aperture of said housing with the effective wavelength that is required for measurements and/or observations.

Abstract
The invention relates to an assembly for illuminating objects with light of different wavelengths in microscopes, automatic microscopes and devices for fluorescent microscopy applications. Said assembly comprises LED light sources for illuminating the objects, which are positioned in the illumination beam path of the microscope or device. A receiving element (6; 13) that can be rotated about a rotational axis (5) is provided with respective fixing elements (7) for at least one LED (3; 3.1). The receiving device (6; 13) is situated in a housing (1) that can be placed on or positioned in the device housing (18). A drive unit (9) for the defined adjustment of the receiving device (6; 13) is provided in such a way that the LED (3; 3.1) can be positioned in front of a light emission opening of the housing (1) with the respective focal point wavelength that is required for measuring and/or observation purposes.
