20090323058 | LASER MICROSCOPE WITH A PHYSICALLY SEPARATING BEAM SPLITTER - The invention proposes a method for imaging at least one microscopic property of a sample and an apparatus with which the proposed method can be carried out. In the method, at least one coherent illumination light with at least one illumination wavelength is produced by means of at least one light source. The illumination light is imaged onto at least one region on or within the sampled. Detection light emitted by the sample is split at least partially into incoherent detection light and into coherent detection light by means of at least on physically separating beam splitter. The coherent detection light is at least partially separated from the coherent illumination light by at least one beam-splitter element. The coherent detection light is detected. The proposed method can be used in particular for investigating the sample by means of coherent anti-Stokes-Raman scattering. | 12-31-2009 |
20100122588 | DEVICE AND METHOD FOR PROVIDING A PREDETERMINABLE CONCENTRATION OF AT LEAST ONE COMPONENT IN A LIQUID MEDIUM - A method and a device for providing a predeterminable concentration of at least one component in a microscopic sample liquid medium are described. The device includes a feeding device for the at least one component. Measurement data are determined, measuring a predeterminable parameter using a microscopic method. The concentration of the at least one component is adjusted or controlled via the feeding device based on the basis of measurement data. | 05-20-2010 |
20120236398 | Phase Filters for a Scanning Microscope - The aim of the invention is an optical device for a scanning microscope, said device enabling the focusing of a light beam largely independent of wavelengths; and thus high-resolution microscopy, in particular STED microscopy, in a wider wavelength spectrum is facilitated. At least two phase filters lie on a support. Advantageously, the support is a filter wheel or a filter slider which can be introduced into the beam path of the light beam, said beam path preferably being the beam path of the stimulating light beam in an STED microscope. Several phase filters preferablylie on the support in the shape of a matrix. The support is designed as a glass substrate on which each phase filter is applied. To achieve said aim, another position is additionally found on the support for adjustment purposes, wherein the wavefront of the light is not influenced when it passes through said position, that is, the position is an empty position on which no phase filter is found. | 09-20-2012 |

20130128025 | Device and Method for Acquiring a Microscopic Image of a Sample Structure - A device and a method for acquiring a microscopic image of a sample structure are described. An optic for imaging the sample structure and a reference structure is provided, as well as a drift sensing unit for sensing a drift of the sample structure relative to the optic on the basis of the imaged reference structure. The optic comprises a first sharpness plane for imaging the sample structure and at the same time a second sharpness plane, modifiable in location relative to the first sharpness plane, for imaging the reference structure. | 05-23-2013 |

20130229494 | MICROSCOPIC DEVICE AND MICROSCOPIC METHOD FOR THE THREE-DIMENSIONAL LOCALIZATION OF POINT-LIKE OBJECTS - A microscopic device provides three-dimensional localization of point-like objects and includes two imaging optics, each configured to image a same point-like object located in an object space into two separate image spaces as a focused light distribution. Two detector units are respectively associated with the imaging optics and configured to capture an analyzable light spot in detection points of a detection surface disposed in the respective image space. Each imaging optics includes an optical device that orients the focused light distributions obliquely to a detection axis such that, taking into account the detection point correspondence, the two light spots shift in opposite directions based on a z-position of the point-like object. An evaluation unit brings the detection points of the two detection surfaces into mutual pairwise correspondence and analyzes the two light spots so as to ascertain a lateral x-y position and an axial z-position of the point-like object. | 09-05-2013 |
