Patent ID: 8203784

Claim:
A multispectral illumination device for a microscope or reader comprising: four exchangeable lighting modules, each light module having a spectral region that is different from the spectral regions of the other light modules; and three exchangeable coupling modules, each with a dichromatic mirror for coaxial superimposition of the light radiation emitted by the lighting modules; wherein the dichromatic mirrors, which are designed as longpass filters, divide the entire spectral region into four color regions; wherein a lighting module lies in one of the four color regions, and the lighting modules and coupling modules are arranged in a binary tree structure; wherein, when exchanging one lighting module for another light module whose spectral region lies in a different color region, the dichromats of the coupling modules are adapted to the individual spectra of the lighting modules arranged in front of them; and wherein each longpass filter is selected in such a way that all individual spectra of the lighting modules in an entire spectrum are available simultaneously at an output of the multispectral illumination device.
