of light. Other microscopes have an iris diaphragm with a lever that opens and closes the diaphragm to let in varying amounts of light. Use the condenser diaphragm to reduce the amount of light and increase the contrast of the image. Condenser Focusing Knob - This control is used to precisely adjust the vertical height of the condenser.

The function of the condenser is not to magnify light in any way, but to manipulate its direction and angles of reflection. The condenser controls how much light from the illuminator is permitted to pass up through the aperture, controlling the intensity of the light. It also, critically, regulates the contrast. In darkfield microscopy, it is ...

In this post, the function of the condenser aperture diaphragm is explained. The purpose of the condenser is to concentrate the light onto the specimen, its diaphragm regulates resolution, contrast and depth of field. Many modern course microscopes are equipped with a condenser and an associated condenser diaphragm. The purpose of the condenser ...

This condenser is useful for both routine and critical laboratory analysis with "dry" objectives and also for black and white or color photomicrography. A critical factor in choosing substage condensers is the numerical aperture performance that will be necessary to provide an illumination cone adequate for the objectives.
