A Multimode Fluorescent Microscope

We present a fluorescent microscope that is available in confocal and total internal reflection mode. The design of the microscope includes two convex lenses in the incident and output stage, which enables the confocal mode; a dichroic mirror, a neutral density filter and a 50/50 mirror that enables the additional spectrometer function. To make the design compact, we utilized cage components, as well as upside-down setup. Our goal in the near future is to use this microscope to observe quantum dot blinking phenomenon
