Electrically driven microscope

A microscope comprising:

• an interchanging device which interchanges a plurality of objective lenses;
• a determination device for determining which of said lenses is disposed in an optical path of the microscope;
• a manually settable adjusting mechanism, disposed in an illuminating system for applying light to a sample, for adjusting an illumination characteristic of the applied light;
• a data storing portion for storing therein plural sets of manual setting information, each set corresponding to a different objective lens and containing information indicating at least one most recent manual setting of said adjusting mechanism for the corresponding objective lens;
• and
• a setting device for reading out the information from the set of manual setting information stored in said data storing portion corresponding to the objective lens determined to be in said optical path by said determination device in association with an interchange effected by said interchanging device, and for electrically controlling said adjusting mechanism based on said read-out information to thereby set the illumination characteristic.

• a manually settable moving device capable of adjusting the position of a stage, on which a sample is placed for observation, along said optical path of the microscope;
• a data storing portion for storing therein plural sets of manual setting information, each set corresponding to a different objective lens and containing information indicating at least one most recent manual setting of said moving device for the corresponding objective lens;
• and
• a setting device for reading out the information from the set of manual setting information stored in said data storing portion corresponding to an objective lens determined to be in said optical path by said determining device in association with an interchange effected by said interchanging device.

An electrically driven microscope comprising:

• a manually settable adjusting mechanism that is adjusted during observation of a sample;
• a driving device to drive said adjusting mechanism electrically;
• a revolver to hold a plurality of objectives and to change an objective disposed in an optical path of the microscope;
• a memory for storing a plurality of manual setting values, each corresponding to a different objective lens and indicating a manual setting of said adjusting mechanism for the corresponding objective lens;
• a determination device to determine which of said lenses is disposed in said optical path;
• and
• a controlling circuit connected to said determination device, said memory, and said driving device, to read out the stored manual setting value corresponding to an objective lens determined to be in said optical path by said determination device, and to output a controlling signal to the driving device so as to set said adjusting mechanism based on the read-out setting value,
• wherein, when a setting of said adjusting mechanism is manually changed during observation, said controlling circuit rewrites the stored manual setting value corresponding to the objective disposed in said optical path to a value indicating the changed setting without altering the other stored manual setting values.
