Question

What controls the amount of light reaching ocular lens?

Answer

Iris Diaphrag is your answer

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.

• Combined, they control both the focus and quantity of light applied to the specimen.
