Definitions

  • the invention relates to an optical coupling element which serves as a connecting piece between a flow cell and a microscopic evaluation device.
  • An essential field of application of this optical coupling element is light and fluorescence microscopy for the examination of samples.
  • these microorganisms or microbial aggregates are characterized microscopically in situ (Strathmann.M., Wingender.J., Flemming, H.-C, Application of fluorescently labeled lectins for the visualization and biochemical characterization of polysaccharides in Biofilms of Pseudomonas aeruginosa, Journal of Microbiological Methods 50, 237-248, 2002).
  • the object of the invention is to develop an optical coupling element for the microscopic characterization of samples in flow cells in order to avoid a direct contact of the lens with the flow solution and thereby to keep the losses in the numerical aperture of the lens as low as possible.
  • the invention replaceable optical coupling element leads to a protection of the lens. Due to the optical coupling element, an additional image plane is laid at the location of the original object plane so as not to have to accept any aperture deterioration. Another possible use of this coupling element is given in the coupling of cryogenic cells in the microscopic beam path.
  • the sample carrier 2 is provided with a micrometer screw 10, via which the table can be moved freely in the Z direction.
  • the optical coupling element is not designed to be interchangeable.
  • an additional opening 12 is provided in the cell 1, via which the desired gas atmosphere is introduced into the cell 1.
  • the gas is pressed through a filter 13 into the cell 1.
  • An advantageous embodiment of the invention is to separate the second converging lens 8 by a transmitter liquid 14 from the nutrient liquid or the markers 15 in order to avoid contamination of the surface of the second converging lens 8.
  • This transmitter liquid 14 is introduced if necessary via a channel 9 in the lid 5.
  • a transmitter fluid 14 are suitable polar liquids that do not dissolve in water and form a meniscus 16 with water-like solutions due to the resulting surface tension.
  • Fig. 2 shows the optical path between the objective 11 and the sample 3.
  • a total of 3 (or 4 when using a transmitter liquid 14, [s Fig. 3]) additional optical active surfaces are inserted to the object (the sample 3) in to image the image plane 18 of the microscope. These are the two lenses and the spaces between them. Between the lens 7 and the lens 11, an additional image plane 19 is generated by the optical coupling element 7,8.
  • Other optically active surfaces can be introduced if color correction is necessary.
  • FIG. 3 shows the formation of a meniscus 16 between the polar transmitter liquid 14 and the bipolar nutrient medium 15.

Abstract

L'objectif de l'invention est de mettre au point un élément de couplage optique pour la caractérisation microscopique d'échantillons dans des cellules à écoulement, cet élément permettant d'éviter un contact direct de l'objectif avec la solution d'écoulement et de réduire ainsi au maximum les pertes au niveau de l'ouverture numérique de l'objectif. L'élément de couplage optique selon l'invention comprend une cellule (1), un ou plusieurs porte-échantillons (2) situés à l'intérieur de cette cellule (1), des amenées et des évacuations (4) pour garantir un flux continu de différentes solutions à travers la cellule (1), ainsi que des ouvertures (12) pour introduire une atmosphère de gaz inerte. L'invention se caractérise en ce qu'un évidement est ménagé dans la partie supérieure (5) pour l'examen microscopique des échantillons (3) in situ, en ce qu'un élément de couplage optique additionnel (7, 8) est placé dans l'évidement de la partie supérieure (5) et en ce que le système optique est constitué de deux milieux optiquement actifs qui sont disposés à l'opposé optiquement l'un vis-à-vis de l'autre.
