Abstract
A confocal optical system includes a light source and a spinning polarizer disposed in the optical pathway such the light emitted from the light source passes through the spinning polarizer. A first objective lens is disposed in the optical pathway to allow passage of light that passes through the spinning polarizer. A microlens array member is disposed adjacent the first objective lens to receive light. The microlens array member includes a plate having a plurality of holes arranged in an array pattern. A second objective lens is disposed in the optical pathway to receive and allow passage of light to a sample. The optical pathway is arranged such that, after reaching the sample, the light is directed back through the second objective lens, the microlens or microlens with filter array, and the first objective lens and a fluorescent filter cube as an emission beam to reach at least one camera which provides an image of the sample.
