    Abstract: A dual-configuration microscope is provided. The microscope may be converted into an upright configuration or an inverted configuration. The microscope includes a base having a lower portion and an upper portion, the lower portion configured to support the microscope. The microscope further includes a body having a first portion, a second portion, and an intermediate portion extending between the first and second portions. The intermediate portion of the body is rotatably coupled to the upper portion of the base at a rotational coupling. The rotational coupling defines a rotating axis that extends in a longitudinal direction with respect to the microscope. The microscope further includes an objective disposed proximal to the first portion and a light source disposed proximal to the second portion.

    Abstract: A device for holding filters for a microscope includes a filter wheel (20) rotatable about an axis of rotation (16) and a drive unit (14) for rotating the filter wheel (20). The filter wheel (20) comprises a basic body (44) rotatable about the axis of rotation (16) and at least one segment (46-54) selectively connectable to the basic body. The segment (46-54) comprises at least two housing areas (58, 59) each holding at least one filter (11). Another housing area may provide a transmission range (36, 59) for unfiltered transmission of light. A second rotatable filter wheel may be arranged at a location displaced along the axis of rotation relative to the filter wheel, and may have its own respective transmission range for unfiltered transmission of light, whereby a filter on either filter wheel may be aligned with the transmission range on the other filter wheel.
