Patent ID: 8625201

Claim:
An optical element for distributing light that has a predefined spectral energy distribution in a predetermined working wavelength range, the optical element comprising: a transparent body into which the light enters, the transparent body comprising a beam splitter layer embodied inside the transparent body, the beam splitter layer having a predefined wavelength-dependent reflectance in the working wavelength range with which it reflects the light entering the transparent body in order to generate a reflected exit light bundle, and a wavelength-dependent transmittance with which the beam splitter layer transmits the light entering the transparent body in order to generate a transmitted exit light bundle; and a compensation layer arrangement embodied on the transparent body separately from the beam splitter layer, the compensation layer arrangement having transmittance with regard to the light passing through the compensation layer arrangement defined as a function of the reflectance and transmittance of the beam splitter layer in such a way that the reflected exit light bundle and the transmitted exit light bundle have, within the working wavelength range, matching spectral energy distributions that differ from one another at most by an amount equal to a wavelength-independent offset value.
