Is condenser and diaphragm the same?
The diaphragm is used to control the amount of light that is entering the condenser and ultimately the amount of light that is reaching the sample. In standard configurations, the diaphragm is located between the light source and the condenser.
What is the job of the condenser and iris diaphragm?
The main function of an iris diaphragm of a microscope is to control the amount of light that reaches the specimen. This light comes from the microscope’s light source, and is gathered by the condenser, before being regulated by the diaphragm, then passing through the specimen.
What is the difference between the condenser and the diaphragm on a microscope?
The aperture diaphragm (also called an iris diaphragm) controls contrast, and is found in the condenser, which sits right below the stage in line with the microscope objectives. The condenser may be movable, both in the horizontal and vertical directions.
How does the function of the condenser differ from the function of the diaphragm?
The purpose of the condenser is to concentrate the light onto the specimen, its diaphragm regulates resolution, contrast and depth of field. The purpose of the condenser is to concentrate the light onto the specimen, its diaphragm regulates resolution, contrast and depth of field.
What is the main function of iris diaphragm?
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.
What is the diaphragm on a microscope used for?
Opening and closing of the condenser aperture diaphragm controls the angle of the light cone reaching the specimen. The setting of the condenser’s aperture diaphragm, along with the aperture of the objective, determines the realized numerical aperture of the microscope system.
Where is the diaphragm located on a microscope?
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.
