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.

Confocal scanning microscope and beamsplitter therefor

The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object. A directing device for alternately directing the images to the left and right eyes of a viewer at a frequency above the flicker frequency of the human eye.

The invention is directed to a confocal incident light microscope for viewing an object. The microscope includes: an illuminating device for transmitting an illuminating beam along an illuminating beam path; a viewing optical assembly for defining a viewing beam path; an optical unit for joining the illuminating beam path and the viewing beam path to form a common beam path; a perforated mask arranged in the common beam path at an angle .delta. to a plane perpendicular to the common beam path; an imaging optic arranged between the perforated mask and the object; a first prism having a first wedge-shaped section arranged in the common beam path between the optical unit and the perforated mask; the first wedge-shaped section defining a wedge angle .alpha. and having a surface essentially parallel to the perforated mask; a second prism having a second wedge-shaped section arranged in the common beam path between the perforated mask and the imaging optic; the second wedge-shaped section defining a wedge angle corresponding to the wedge angle .alpha. and having a surface essentially parallel to the perforated mask; the first and second prisms being arranged in the common beam path so as to be rotated by 180.degree. relative to each other; and, the first and second prisms defining the wedge angle .alpha.:

An arrangement generates a projection beam path on the projection objective outside of the optical axis. This is achieved by mounting an optically transparent wedge forward or rearward of the test pattern. The wedge can be rotated with respect to its orientation by 180.degree..
