GENERAL HISTOLOGY

Detailed explanation-1: -Diopter Adjustment: When you look through a microscope with two eyepiece lenses, you must be able to change the focus on one eyepiece to compensate for the difference in vision between your two eyes. The diopter adjustment does this.

Detailed explanation-2: -Coarse Adjustment Knob-The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus.

Detailed explanation-3: -Microscope Diopter This is a simple turning device which is either attached to the outside of an eyepiece tube of a binocular head, or to the eyepiece itself. When the diopter is turned, it raises or lowers the eyepiece in order to adjust the focus for each eye. This improves the magnification and also the clarity.

Detailed explanation-4: -Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).

Detailed explanation-5: -Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses and can be rotated to easily change power. Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope.
