GENERAL HISTOLOGY

Detailed explanation-1: -Iris Diaphragm controls the amount of light reaching the specimen. It is located above the condenser and below the stage. Most high quality microscopes include an Abbe condenser with an iris diaphragm.

Detailed explanation-2: -Transmitted light usually gets to the specimen from below the stage by means of an illuminator. It’s the most frequently used lighting for compound, high-power microscopy. The simplest illuminator is a pivoted mirror to beam external light to the microscope.

Detailed explanation-3: -A simple light microscope manipulates how light enters the eye using a convex lens, where both sides of the lens are curved outwards. When light reflects off of an object being viewed under the microscope and passes through the lens, it bends towards the eye. This makes the object look bigger than it actually is.

Detailed explanation-4: -(B) Optical Parts of Compound Microscope The object’s magnified image can be observed with the help of an eyepiece. A mirror is found attached wither to the pillar or the lower end of the arm.
