Spinning Disk (Nipkow Disk) Microscope

A Nipkow spinning disk microscope is one type of Fluorescence Microscope. A Nipkow disk is simply a spinning disk with a series of equally distanced circular holes of equal diameter drilled in it. It was invented by Paul Nipkow in 1884. Applied to a Fluorescence Microscope, it allows the sample to be scanned with an array of light points transmitted through these holes, participating in some of the advantages of a Confocal Microscope. A Yokogawa Disk is a Nipkow disk with an array of microlenses in (or right after) the holes used in many commercial spinning disk microscopes.
