Condenser lens

Definition

A condenser lens is an optical component in a microscope that focuses light onto the specimen, enhancing illumination and image clarity. It is crucial for achieving high-resolution images in microscopy.

5 Must Know Facts For Your Next Test

1. Condenser lenses are located beneath the stage of a microscope.
2. They work by gathering light from the microscope's light source and concentrating it into a cone of light that illuminates the specimen.
3. Adjusting the condenser lens can improve contrast and resolution in microscopic images.
4. High-quality condenser lenses often include an iris diaphragm to control the amount of light passing through.
5. Proper alignment of the condenser lens with the objective lens is essential for optimal image quality.
