Microscope condenser with an integrated catch pan

Lens change-over device with centerable reception rings

A microscope support foot (10) includes a central portion (14) and two lateral portions (15, 16), which form receiving chambers (19, 20, 21) by means of separating walls (17, 18) extending as far as a base plate (23). The optical components for an illumination arrangement (28) are disposed in receiving chamber (20) so as to be protected from dust by a seal (25), and the electronic components are disposed in a heat-dissipating manner in the receiving chamber (21), so that the heat-emitting components are in contact with the base plate (23) which is made of heat-dissipating material. This base plate and the lateral portion (16) have ventilation slits (42, 42'). A drive unit (36) for the adjustment of the successviely arranged aperture stop and light field stop (30, 31) is secured in the receiving chamber (19) in such a manner that the adjusting arrangement is accessible from outside and is disposed at a convenient distance from a focussing arrangement (13).

Microscope frame

Disclosed is a microscope adapted for accepting one or more attachment illuminating devices, which have different dimensions and are designed to be supplied with electric power either from a source within the microscope or external to the microscope. The microscope comprises a microscope stand comprising a base and a vertical support member; at least one source of electrical energy located inside of the stand for powering an illuminating device; and first means, associated with the stand, for connecting any of a variety of attachment illuminating devices which have different dimensions and are designed to be supplied with electric power either from the electrical energy source or from an electrical energy source external to the microscope. This connecting means includes means, adapted to cooperate with complementary coupling means on each attachment illuminating device, for mechanically coupling an attachment illuminating device, and means, adapted to cooperate with complementary electrical coupling means on each attachment illuminating device which is designed to be supplied with electrical energy from the electrical energy source, for electrically coupling the electrical energy source with an attachment illuminating device which is designed to be supplied with electrical energy from said electrical source. Thus, the attachment means provide for direct standardized attachment of all attachment illuminating devices having different dimensions without the use of any size adapting means.

Microscope with attachable illuminating devices

Disclosed is a microscope stand which permits a lens turret and an eyepiece mounted on the stand to be mounted close enough together to eliminate the necessity of an intervening tube lens. In permitting this mounting of the lenses, a recess is provided in the stand which substantially weakens the mounting structure. Vertical webs are provided in the preferred embodiment which extend adjacent the recess and external to the lens turret which strengthen the microscope stand and mounting structure.

Microscope stand with protected turret

An apparatus for varying the position of a field stop with respect to a microscope substage illuminator includes a carrier for slidably mounting the field stop on the illuminator so as to move in a direction transverse to the optical axis of the illuminator. An annular element controlling the aperture of the field stop is pivotally mounted within the carrier and is coupled to a knurled ring projecting radially and upwardly from the diaphragm carrier. The knurled ring is in turn pivoted within the diaphragm carrier and preferably carries a circular line inscribed thereon which is concentric with the field stop in order to facilitate adjustment of the field stop.
