GENERAL HISTOLOGY

Detailed explanation-1: -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. They almost always consist of 4X, 10X, 40X and 100X powers.

Detailed explanation-2: -When carrying a compound microscope always take care to lift it by both the arm and base, simultaneously. There are two optical systems in a compound microscope: Eyepiece Lenses and Objective Lenses: Eyepiece or Ocular is what you look through at the top of the microscope.

Detailed explanation-4: -The revolving nosepiece is the inclined, circular metal plate to which the objective lenses, usually four, are attached. The objective lenses usually provide 4x, 10x, 40x and 100x magnification.

Detailed explanation-5: -On most models, the revolving nosepiece attaches to the lower portion of the microscope’s arm. The revolving nosepiece is round and generally has three or four cone-shaped lenses attached to it. The revolving nosepiece may have a serrated edge to assist the user in gripping and turning the nosepiece.
