Abstract

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).

Claims5

Dependent claims

A microscope support, comprising:

a base having a central portion and respective side portions integral with the central portion;
a base plate covering the bottom of said base;
an upright member for supporting a microscope, extending upwardly from the central portion of the base;
means, mounted on the upright, for focussing the microscope;
partition means, within the base and cooperating with said base plate, for defining a central receiving chamber in the central portion and side receiving chambers in each of the side portions of the base, said partition means comprising separating walls and a thermally insulating seal disposed between the separating walls and the base plate;
elements of an optical illuminating system disposed within the central receiving chamber;
electrical and electronic components of the illuminating system disposed in a first of the side receiving chambers;
means, associated with said first side receiving chamber, for conducting heat generated by said electronic components away from said components, said heat conducting means being in direct contact with said components;
and
an adjustment mechanism for said optical illuminating system mounted on one of said side portions at a finger access distance from said focussing means.
