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.

Detailed explanation-2: -Most compound microscopes come with interchangeable lenses known as objective lenses. Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively.

Detailed explanation-3: -A turret or revolving nosepiece of a microscope is a part that holds objective lenses (can be two or many). The vital role of the nosepiece is to rotate those objective lenses and help to change the magnification power.

Detailed explanation-4: -It uses two separate optical paths with two objectives and two eyepieces to provide slightly different viewing angles to the left and right eyes. In this way it allows a three-dimensional visualization of the sample.

Detailed explanation-5: -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.
