Abstract

A novel attachment for a microscope to be coupled to an optical coupling tube of a microscope. The attachment for a microscope includes a light source generating a quasi-collimated light output. Elements are provided for reflecting the light output from the light source towards a specimen in the microscope. Further, elements are provided for propagating a reflection of the light output from the light source from the specimen to a viewing point. The elements for achieving the reflecting and the elements for achieving the propagating may each include a spinning Nipkow disk and a dichroic mirror. The quasi-collimated light output from the light source directly impinges on the Nipkow disk, i.e., without being focused on the Nipkow disk and without passing through a lens. A right angle mirror can also be positioned as one of the elements for achieving the reflecting and the propagating.
