Abstract
The invention is directed to a confocal scanning microscope for viewing an object. The confocal scanning microscope includes an illuminating device for transmitting an illuminating beam along an illuminating beam path and an optic for defining an imaging beam path. A beamsplitter is mounted in the imaging beam path and has a partially reflecting layer for deflecting a component of the illuminating beam toward the object whereby the component is reflected back toward the beamsplitter and passes through the beamsplitter into the imaging beam path with unwanted reflections occurring within the beamsplitter. The beamsplitter has two prisms conjointly defining the partially reflecting layer and has an external form defined by the optical faces of the prisms with each two mutually adjacent ones of the optical faces conjointly defining an angle unequal to 90.degree. whereby the unwanted reflections are substantially prevented from entering the imaging beam path.
