The oblique-illumination system can be used to illuminate from any desired direction the surface of an object located at a fixed known offset away from a sample solution containing fluorescently tagged targets. Oblique illumination is used to illuminate features of the surface while epi-illumination is used to create fluorescent light emitted from the tagged targets. The combination of oblique illumination of the surface and epi-illumination of the targets enables capture of images of the surface features and the fluorescent targets so that the locations of the targets in the sample can be determined based on the locations of the surface features. | 07-04-2013 |
| 20140092469 | Method and System for Optical Microscopy - Optical microscopy of biological specimens, particularly live cells, is difficult as they generally lack sufficient contrast to be studied successfully as typically the internal structures of the cell are colourless and transparent. Commonly, contrast is increased by staining the different structures with selective dyes, but this involves killing and fixing the sample. Staining may also introduce artifacts, apparent structural details caused by the processing of the specimen and are thus not a legitimate feature of the specimen. Further, microscopy of different elements of these biological specimens typically requires multiple microscopy techniques on multiple specimens. According to embodiments of the invention simultaneous imaging techniques are applied to a biological specimen such as fluorescent imaging and dark field imaging by designing an experimental evaluation system and associated illumination system addressing the conflicting demands of these approaches. | 04-03-2014 |
