A compound microscope has two sets of lenses (objective and eyepiece) that magnify the specimen. In contrast, a simple microscope only has one lens. Additionally, compound microscopes are typically used for higher magnification and resolving power compared to simple microscopes.
A compound microscope uses multiple lenses in its system to magnify the image multiple times, allowing for higher powers of magnification compared to a simple microscope that only uses one lens. The compound microscope's use of objective and eyepiece lenses working together in a series enlarges the image, making it appear larger and clearer.
A compound microscope typically ranges in size from 10-20 inches in height, with the base being around 6-8 inches wide. The specific dimensions can vary based on the manufacturer and model of the microscope.

Compound microscopes (also called compound light microscopes) employ light and an array of glass lenses to magnify an object. (This is distinguished from a simple microscope of one lens.) An electron microscope uses a beam of electrons to magnify an object. The lensing system employs electric and magnetic fields and is specialized for applications requiring much higher magnification.

After leaving the condenser in a compound light microscope, light passes through the specimen on the slide.

The parts of a compound microscope include the eyepiece, objective lens, stage, condenser, focus knobs, and light source. The eyepiece magnifies the image produced by the objective lens, while the objective lens collects light and magnifies the specimen. The stage holds the specimen in place, and the condenser focuses light onto the specimen. The focus knobs adjust the focus of the image, and the light source illuminates the specimen.
After leaving the condenser in a compound light microscope, the light passes through the specimen on the slide. The light is then refracted and magnified by the objective lens, and further magnified by the eyepiece before reaching the eye of the observer.
You can adjust the amount of light that passes through the specimen on a compound microscope by adjusting the condenser. Lowering the condenser increases the amount of light, while raising it decreases the intensity of the light. Additionally, you can also adjust the light intensity using the light source controls on the microscope.
The function of a condenser in a microscope is to focus and direct light onto the specimen being observed. It helps to illuminate the specimen evenly and maximize the resolution and contrast of the image. The condenser also plays a role in controlling the amount of light entering the microscope.
The condenser knob in a microscope is used to adjust the position of the condenser lens, controlling the amount of light that reaches the specimen. By adjusting the condenser knob, the user can optimize the illumination and contrast of the specimen being viewed under the microscope.

To create contrast when using a compound light microscope, you can adjust the microscope's condenser to control the amount of light reaching the specimen. Additionally, you can use stains or dyes on the specimen to enhance contrast by highlighting specific features.
The student should adjust the condenser to allow more light to pass through the specimen in a compound light microscope. By adjusting the condenser height or iris diaphragm, the amount of light reaching the specimen can be controlled for better visibility.

The function of a condenser lens is to focus the light onto a specimen. Condenser lenses are most useful at the highest powers of 400 x and above. Microscopes with a condenser lens render a sharper image than those with no lens. These lenses are able to move up and down.
