Abstract:
A method for separating fluorescence spectra of dyes present in a specimen (15) is disclosed. Firstly a spectral scan of the fluorescence spectrum of all the dyes present in the specimen (15) is performed. The fluorescence spectra associated with the respective dyes are stored in a database of the computer system. After spectral deconvolution of the acquired mixed fluorescence spectrum, a comparison is made between the measured individual spectra ascertained by spectral deconvolution and the fluorescence spectra associated with the respective dyes. Lastly, a linear deconvolution of the acquired mixed fluorescence spectrum is performed.
Abstract:
A microscope system and a method that record spectra (60a, 61a, 62a, 63a, and 66a) of the dyes present in the specimen (15) using an SP module (20) are disclosed. A transformation of the data of the ascertained spectra, and of the dye spectra (60b, 61b, 62b, 63b, and 66b) stored in a database, is performed. The spectra are entered into a correspondingly into a divided transformation space. Allocation of the dye spectra (60b, 61b, 62b, 63b, and 66b) to the measured spectra (60a, 61a, 62a, 63a, and 66a) is accomplished by way of a comparison in the transformation space.
Abstract:
A method and a system for the analysis of co-localizations of dyes present in a specimen. The fluorescence spectra of the dyes present in the specimen are determined. A tolerance region around each of the fluorescence spectra is selected. The spectra of the specimen, in which at least two dyes are present, are then acquired pixel by pixel. Those spectra that lie within the tolerance region around the fluorescence spectra are then calculated. A lambda vector is calculated for each pixel and assigned to a spectrum. Images can be displayed in accordance with the assignment to the spectra.

A spectral scanning microscope and a method for data acquisition using a spectral scanning microscope are disclosed. A computer system is provided that encompasses a memory and a database. In combination with the computer system and/or the database, a continuous wavelength subregion that serves to illuminate the specimen can be selected from a continuous wavelength region using the spectral selection means. Also in combination with the computer system together with the spectral selection means, a detection band can be selected from the detected light beam.

A method and an arrangement for automatic three-dimensional recording of structures of interest in a sample (15) are disclosed. The arrangement possesses a microscope having at least one microscope objective (13). The images of a sample (15) are acquired using a detector unit (19). A computer system (23) controls acquisition of the images and the microscope functions. The computer system (23) possesses a means (25) for automatically recording the entire marked specimen region in three dimensions.
Abstract:
A microscope system includes at least one lens that defines an illumination field and at least one light source that emits an illuminating light beam for illuminating a specimen through the lens. At least one detector is provided for, pixel-by-pixel, detecting a detection light beam coming from the specimen. An electronic circuit is connected downstream from the detector, the electronic circuit including a memory unit for storing a wavelength-dependent brightness distribution of an illumination field of the at least one lens. The electronic circuit employs, pixel-by-pixel, the stored wavelength-dependent brightness distribution so as to form a homogeneously illuminated image field. An actuatable element is provided for controlling, pixel-by-pixel, an intensity of the illuminating light beam as a function of the stored wavelength-dependent brightness distribution so as to homogeneously illuminate the illumination field.
Abstract:
In an optical device (2), in particular a microscope, drift is sensed by the fact that a first image of an immovable specimen (30) is acquired at a first time (T(n-1)), and a second image thereof at a second time (T(n)). The drift is calculated from a comparison between the first and the second image.
Abstract:
This invention comprises a method, a software, and a microscope system for monitoring and controlling information loss. The observation of information that is not present and the comparison of ideal loss to actual loss generates an explanatory component by means of a rule set. The user is instructed by the microscope system in an appropriate manner, for example by means of a display, to undertake actions that remove the defects.
Abstract:
A method and system for analyzing acquired scan data are disclosed. The method involves measuring physical values of a particular process, converting the measured values into two signals, such as electrical signals, and then converting the two signals into polar coordinates by defining a vector having a radial magnitude and a vector angle corresponding to the magnitudes of the two signals. The method further provides for validation and visual representation of the measured physical values by employing the angle information to define the upper and lower bounds of the acceptable measured values. The corresponding system comprises sensors measuring the two physical values and yielding the two signals. A signal processing unit receives the two signals, converts them into a pair of polar coordinates defines by the magnitude of the two signals.
