An illumination apparatus includes a first solid-state-based illumination module, a second solid-state-based illumination module, and a superposition unit, which couples first and the second luminescence radiation into an illumination beam path, in which said radiation is guided up to the end of the illumination beam path in order to illuminate a light modulator. A filter unit which filters light with a second color from the first luminescence radiation with a first color and from the second luminescence radiation such that light with the first and second color is present at the end of the illumination beam path.

Illumination device for a projector having a light modulator

An illumination apparatus for a projector that includes a light modulator is provided. The illumination apparatus includes a first illumination module emitting first radiation, a second illumination module emitting second radiation, a light mixing rod extending in the axial direction and a superposition unit, which superposes the first and second radiation and couples this into the light mixing rod. The superposition unit includes a first imaging optical unit which focuses the first radiation into the light mixing rod such that a first focus is present, and a second imaging optical unit which focuses the second radiation into the light mixing rod such that a second focus is present. The first focus is spaced apart from the second focus in the axial direction.

The invention relates to an apparatus and a method for determining a defocussing value (&#x394;z, &#x394;z, &#x394;z) for at least one image feature in an image, wherein at least one monochromatic image of an object is generated, wherein the defocussing value (&#x394;z, &#x394;z, &#x394;z) is determined on the basis of the image and depending on the wavelength (&#x3bb;) of the monochromatic image, and a method and apparatus for image-based determination of a dimensional size.

Method and apparatus for determining a defocusing valve and for image-based determination of a dimensional size

An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X, Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.
