Diy beam expander
WebApr 23, 2024 · Since the reflective beam expander is eventually attached to the back-port of a standard microscope (Olympus IX-83), the focal spot can be imaged through one of the oculars when focusing into e.g. a concentrated fluorophore solution. There, the focus appears (rather strongly) elongated in one axis rather than symmetric.
