A dual stereo-compound microscope that is enabled to change between stereoscopic observation and compound observation while illuminating a sample with illumination. While shifting between a stereoscopic view and a compound view, the sample being viewed remains parcenter and parfocal.

A system that permits biological samples to be viewed in three optical ways, including in three dimension (stereoscopic), two dimension (compound optic), and macro with reflected light fluorescence. Each of three optical views can be carried out on one system. The system permits the user to sort samples under stereo fluorescence illumination and to verify structural detail under compound optic fluorescence illumination on one instrument. The three position rotating objective carrier with automatic shift houses one stereoscopic and two compound objectives. All objectives are parcenter and parfocal.

A reflective light fluorescence system that functions on a stereo microscope with two distinct optical paths to illuminate samples that have been stained with a fluorochrome or that may exhibit autofluorescence. The stereo microscope includes a source of illumination and a filter module with two dichroic mirrors, for sending an excited wavelength of the illumination equally down both optical axes to excite the sample uniformly. A portion of the illumination light passes through the first dichroic mirror, which is preferably about 50% dichroic, to the second dichroic mirror, while the remaining light is reflected down one optical path of the microscope. The second dichroic mirror, which is preferably about 100% dichroic, reflects 100% of the remaining portion of the illumination light down the second optical path. Thus, the sample is uniformly excited by the illumination light reflected down both optical paths. The resulting emitted signal is transmitted from the sample up through the optical paths equally.
