20140133017 | Imaging Distal End of Multimode Fiber - Where a multimode fiber is used for light delivery in a microscope system and a transverse distribution of light exiting a distal end of the fiber is substantially uniform, the distal end is imaged onto a plane of a sample to be probed by the microscope system, or at a conjugate plane. Alternatively, the distal end is imaged onto a plane sufficiently close to the sample plane or the conjugate plane such that a radiant intensity of light at the sample plane or the conjugate plane is substantially uniform. In the case of a multi-focal confocal microscope system, the distal end of the multimode fiber is imaged onto a plane of a segmented focusing array. Alternatively the distal end is imaged onto a plane sufficiently close to the segmented focusing array plane such that a radiant intensity of the light at the segmented focusing array plane is substantially uniform. | 05-15-2014 |
20140104681 | Spatial Filter to Combine Excitation Light and Emission Light in an Episcopic Multiplexed Confocal Scanning Microscope - In an episcopic multiplexed confocal scanning microscope system, a spatial filter is placed at a conjugate plane to a back aperture plane at a back aperture of an objective lens. The spatial filter is used to combine excitation light and emission light from a multiplexed confocal microscope module. | 04-17-2014 |
20140104680 | Total Internal Reflectance Fluorescence (TIRF) Microscopy Across Multiple Wavelengths Simultaneously - A multiple wavelength total internal reflection fluoresence (TIRF) microscopy system has an objective. A dispersion unit of the system comprises a high-dispersion optical element. The dispersion unit receives illumination light having at least a first wavelength λ | 04-17-2014 |
20130010353 | Multi-Mode Fiber Optically Coupling a Radiation Source Module to a Multi-Focal Confocal Microscope - 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. | 01-10-2013 |
