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: -Nosepiece is the circular structure where the various objective lenses are screwed in. to vary the magnification power, simply rotate the turret. A normal microscope has three or four objective lenses with various magnifications, screwed within a circular “nosepiece” which can be rotated to pick the specified lens.

Detailed explanation-3: -Objective Lenses Most compound microscopes come with three or four objective lenses that revolve on the nosepiece. The most common objective lenses have power of 4X, 10X and 40X. Combined with the magnification of the eyepiece the resulting magnification is 40X, 100X and 400X magnification.

Detailed explanation-4: -NOSEPIECE-A circular plate with 4 objective lenses that can be rotated into position for different magnifications. 10. OBJECTIVE LENS-Four separate lenses that magnify the image (4X, 10X, 40X and 100X) depending on the objective in use.

Detailed explanation-5: -Revolving Nosepiece or Turret: This is the part of the microscope that holds two or more objective lenses and can be rotated to easily change power (magnification). 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.
