prism illuminator (medicine)


prism illuminator
<microscopy> A 45 to ~0-degree prism interposed in the tube of a light microscope for the purpose of directing an intense beam of light through the objective onto the object. The prism illuminator utilises about one half the aperture of the objective as does the mirror illuminator with an attending loss of resolution over that obtainable with either a plane glass illuminator or a pellicle mirror.
