GENERAL HISTOLOGY

Detailed explanation-1: -Compound microscopes usually include exchangeable objective lenses with different magnifications (e.g 4x, 10x, 40x and 60x), mounted on a turret, to adjust the magnification. These microscopes also include a condenser lens and iris diaphragm, which are important for regulating how light hits the sample.

Detailed explanation-2: -Enlargement or magnification of a specimen is the function of a two-lens system; the ocular lens is found in the eyepiece, and the objective lens is situated in a revolving nose-piece. These lenses are separated by the body tube.

Detailed explanation-3: -A convex lens is a converging lens, which means that as light waves travel through all of it, they converged at a position. As a result, they are utilized as the microscope’s objective lens in situations where a precise focus on the object is necessary.

Detailed explanation-4: -The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.

Detailed explanation-5: -By adding an auxiliary lens, you can either increase or decrease magnification however the working distance will change. Reduction lenses (1.0X or less) increase working distance whereas the 1.5X and 2.0X lenses decrease the working distance significantly.
