Abstract
A transmitted-light illumination arrangement for microscopes has at least one LED which is arranged interchangeably in or in the vicinity of the plane of the aperture diaphragm of illumination optics or in front of Köhler illumination optics. The transmitted-light illumination arrangement advantageously has at least one LED light source radiating in the illumination direction of the microscope and at least one LED light source radiating in the opposite direction, wherein the light of the oppositely radiating light source is deflected in the illumination direction via deflecting mirrors, preferably a concave mirror, this light source being located in the focal point thereof.
Claims7
A transmitted-light illumination arrangement for a microscope comprising:
- an illumination optics having an aperture diaphragm and a field diaphragm;
- a first receptacle disposed in the vicinity of the aperture diaphragm;
- a second receptacle disposed in the vicinity of the field diaphragm;
- and
- at least one LED which can be interchangeably positioned in the first receptacle to provide LED light through an aperture of the aperture diaphragm or the second receptacle to provide LED light through an aperture of the field diaphragm of the illumination optics.
A transmitted-light illumination arrangement for a microscope comprising:
- an illumination optics having an aperture diaphragm positioned below a microscope stage and a field diaphragm positioned below the aperture diaphragm;
- a first receptacle disposed in the vicinity of the aperture diaphragm;
- a second receptacle disposed in the vicinity of the field diaphragm;
- and
- a light emitting diode (LED) module having at least one LED, the LED module capable of being interchangeably received in either the first receptacle to provide LED light through an aperture of the aperture diaphragm or the second receptacle to provide the LED light through an aperture of the field diaphragm.
