The iris in an optical microscope is a diaphragm located beneath the stage used to control the amount of light that passes through the specimen. By adjusting the size of the iris, the amount of light entering the microscope can be regulated to optimize the image quality and contrast.
A light microscope uses visible light to magnify and view specimens, offering lower magnification and resolution compared to a scanning electron microscope (SEM) which uses a focused beam of electrons to image the sample, providing higher magnification and resolution. SEM can produce 3D images of the sample surface while light microscopes typically provide 2D images.
Cytology is the branch of biology that focuses on the study of cells, their structure, function, and interactions with other cells. It involves the examination of cells under a microscope to understand their characteristics and behavior. Cytology plays a critical role in various fields such as medicine, research, and forensics.
No, it is best to clean the oil from the 100x objective lens using lens paper or a clean cloth specifically made for cleaning lenses before putting the microscope away. Leaving oil on the lens can attract dust and debris, leading to a blurry image and potentially damaging the lens.
The magnifying system in a microscope typically consists of the objective lens, eyepiece lens, and sometimes a condenser lens. The objective lens is responsible for capturing the image of the specimen, while the eyepiece lens further magnifies the image for the viewer. The condenser lens helps focus the light onto the specimen for clearer viewing.

The diaphragm in a microscope controls the amount of light that passes through the specimen. By adjusting the diaphragm, you can regulate the brightness and contrast of the image, allowing for clearer observations.
The function of an iris diaphragm on a microscope is to adjust the size of the aperture, controlling the amount of light entering the lens system. By changing the diameter of the iris diaphragm, you can adjust the depth of field and improve image contrast and clarity.
