Question

Which of the following regulates the amount of light passing through the slide specimen on the microscope stage ?

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

Answer 2

Iris Diaphragm regulates the amount of light passing through the slide specimen on the microscope stage.

• The Iris diaphragm is located above the condenser and below the stage.
• The condenser collects and concentrates the light obtained from the illuminator and passes it on the specimen placed on the stage.
• A stage is a place where the specimen is placed.
• High-quality microscopes contain additIonal attachments of the Abbe condenser along with the diaphragm.
• Both of these attachments help to focus and determine the quantity of light applied to the specimen.
