According to the present invention there is provided a method for enantiomeric enrichment of a mixture of two enantiomers of a chiral compound, the method comprises the application of the mixture of two enantiomers of a chiral compound onto a surface of a support material for producing a coated support, the determination a first value of an optical activity (OA) of the coated support, the irradiation of the coated support with a light beam having an intensity at least higher than a desorption threshold of one of the enantiomers from the coated support, wherein, if the support material is achiral, the light beam is circularly polarized and, if the support material is chiral, the light beam is unpolarized, linearly polarized or circularly polarized, and the determination of a second value of the optical activity (OA) of the coated support after said irradiation, wherein the second value of the optical activity (OA) differs from the first value of the optical activity (OA).

Method for enantiomeric enrichment

Disclosed herein is a device () for multicolor optical imaging of a sample () with wavelength-dependent optical path length enhancement, the device () comprising an optical resonator () for enhancing an optical path length, wherein the optical resonator () has a first finesse at a first wavelength and a second finesse at a second wavelength; a sample holder () for mounting the sample () in the optical resonator (), wherein the sample holder () is configured to hold the sample () such that an optical axis () of the optical resonator () intersects with the sample ();a first imaging system () for imaging the sample () at the first wavelength with a first imaging technique, and a second imaging system () for imaging the sample () at the second wavelength with a second imaging technique, wherein the second wavelength is different from the first wavelength; wherein the first finesse and the second finesse are chosen such that the optical resonator () enhances a first image quality indicator of the imaging with the first imaging system () and a second image quality indicator of the imaging with the second imaging system ().
