  • Patent number: 10054772
    Abstract: An optical system for endoscopes for which the corrections of the geometrical optical aberrations for multiple wavelengths meet the diffraction limit of the optical system. The optical system is categorized by lens groups. The glass selection for each of these lens groups uses the Hartmann Dispersion Formula. For the glasses in each lens group, limited ranges for the ?o value of the Hartmann Dispersion Formula are set. These ranges are set based on the contribution of the individual lens groups to the overall chromatic aberrations.

  • Patent number: 8275226
    Abstract: A multi-mode optical fiber delivers light from a radiation source to a multi-focal confocal microscope with reasonable efficiency. A core diameter of the multi-mode fiber is selected such that an etendue of light emitted from the fiber is not substantially greater than a total etendue of light passing through a plurality of pinholes in a pinhole array of the multi-focal confocal microscope. The core diameter may be selected taking into account a specific optical geometry of the multi-focal confocal microscope, including pinhole diameter and focal lengths of relevant optical elements. For coherent radiation sources, phase randomization may be included. A multi-mode fiber enables the use of a variety of radiation sources and wavelengths in a multi-focal confocal microscope, since the coupling of the radiation source to the multi-mode fiber is less sensitive to mechanical and temperature influences than coupling the radiation source to a single mode fiber.

  • Patent number: 7864380
    Abstract: In a scanning microscope, slides are fed automatically from a magazine to the imaging system. Each slide is labeled in some fashion with information for selecting the appropriate modality of operation of the scanner for that slide and the modality is implemented automatically. The information is preferably tied to and defined by a laboratory information system (LIS). For example, the instructions may regard the type of microscopy (i.e., trans- or epi-illumination), multi-spectral imaging with particular spectral bands combined with a particular set of z-positions, alternative filters, settings for the numerical aperture of the condenser, alternative detector operation for different resolutions, and alternative post-scan analyses of the data, as deemed optimal for the scan. The label may also contain the slide's identity, a pathologist's name, desired post-scan handling protocol, etc. The preferred array microscope to carry out the invention is also described.

  • Patent number: 7864369
    Abstract: An imaging apparatus consists of multiple miniaturized microscopes arranged into an array capable of simultaneously imaging respective portions of an object. A continuous linear translation approach is followed to scan the object and generate multiple image swaths of the object. In order to improve the quality of the composite image produced by concatenation of the image swaths, the performance of each microscope is normalized to the same base reference for each relevant optical-system property. Correction factors are developed through calibration to equalize the spectral response measured at each detector, to similarly balance the gains and offsets of the detector/light-source combinations associated with the various objectives, to correct for geometric misalignments between microscopes, and to correct optical and chromatic aberrations in each objective.
