The focusing operation of a microscope, control rotary knobs which receive the motion of fingers or hand of an operator to change the focus position relative to a sample under observation. Two of the control rotary knobs are on a common shaft and coaxial with one another and rotationally fixed with respect to one another, and are connected to a position encoder. A toggle switch which is connected to the control circuit and can be actuated by touching or moving one or both rotary control knobs. Whereby the drive circuit is configured such that it generates, as a function of the rotation of the two rotary knobs and as a function of the actuation or position of the toggle switch, a rough or fine adjustment of the focus position relative to the sample under observation.

Operating device for the focusing operation of a microscope

The invention is directed to a temperature-controllable objective, particularly for microscopes and other optical equipment, which comprises a main barrel as the main component part of the objective. The main barrel contains at least one correction mount, cylinder sleeves, mounting rings, carrier rings and/or adjusting rings, and imaging optical elements. In order to control the temperature, at least one structural component part of the objective or an element arranged between structural component parts of the objective is constructed as a temperature-controllable element or as a temperature-controllable foil which is connected (not shown) by leads to a device for monitoring temperature. Further, a temperature gauge or temperature sensor is arranged in the objective and is likewise connected to the device for monitoring temperature.

Temperable lens, especially for microscopes

A method for controlling a changing magazine for microscopes which combines the simple principle of a catch with a &ldquo;forward looking&rdquo; operation having a determined traveling speed profile along path v(x) which can be determined beforehand corresponding to the catch positions x which are assumed to be known. Accordingly, the braking process can be initiated already before reaching the capture area, that is, before the catch signal is initiated. In contrast to the free positioning with a stepping motor or position-regulated driving device, no particular precision is required because the capture area of the catch mechanism is capable of compensating for greater tolerances.
