The total magnification of a microscope equals the magnification of the eyepiece times the magnification of the objective. Diopter–Technically the diopter is a measure the correction value of a lens. It equals the reciprocal of the focal length in meters. If a lens can focus at 1 meter it has a diopter of 1.

What is the stage of a microscope?

All microscopes are designed to include a stage where the specimen (usually mounted onto a glass slide) is placed for observation. Stages are often equipped with a mechanical device that holds the specimen slide in place and can smoothly translate the slide back and forth as well as from side to side.

What is the slide holder on a microscope?

Description. The slide holder on a microscope is an important component for observing specimens by holding your slides secure and steady during observation.

What is the iris diaphragm on a microscope?

Medical Definition of iris diaphragm

: an adjustable diaphragm of thin opaque plates that can be turned by a ring so as to change the diameter of a central opening usually to regulate the aperture of a lens (as in a microscope)

What does the body tube do on a microscope?

The microscope body tube separates the objective and the eyepiece and assures continuous alignment of the optics.

What is the function of eyepiece in compound microscope?

It is so named because it is usually the lens that is closest to the eye when someone looks through the device. The objective lens or mirror collects light and brings it to focus creating an image. The eyepiece is placed near the focal point of the objective to magnify this image.

What does the objective lens do on a light microscope?

The objective itself is usually a cylinder containing one or more lenses that are typically made of glass its function is to collect light from the sample. Microscope objectives are characterized by two parameters: magnification and numerical aperture. The magnification typically ranges from 4× to 100×.

What type of lens is used in compound microscope?

A compound microscope is made of two convex lenses the first the ocular lens is close to the eye and the second is the objective lens.

Which parts of the microscope contain lenses that can magnify the image of a cell?

Above the stage and attached to the arm of the microscope is the body tube. This structure houses the lens system that magnifies the specimen. The upper end of the tube contains the ocular or eyepiece lens. The lower portion consists of a movable nosepiece containing the objective lenses.

Which are the part of compound microscope that controls light intensity and how?

Answer: Explanation: Iris Diaphragm controls the amount of light reaching the specimen.

What is the difference between the condenser and the iris diaphragm?

What is the iris diaphragm? It is located below the stage of a microscope and functions to collect Light and direct it onto the object being examined. The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above).

What does the coarse focus knob do on a microscope?

COARSE ADJUSTMENT KNOB — A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.

Where is condenser on microscope?

the stage
On upright microscopes the condenser is located beneath the stage and serves to gather wavefronts from the microscope light source and concentrate them into a cone of light that illuminates the specimen with uniform intensity over the entire viewfield.

What does the rheostat do on a microscope?

rheostat – alters the current applied to the lamp to control the intensity of the light produced condenser – lens system that aligns and focuses the light from the lamp onto the specimen diaphragms or pinhole apertures – placed in the light path to alter the amount of light that reaches the condenser (for enhancing …

What is the difference between a compound microscope and a stereomicroscope?

A compound microscope is generally used to view very small specimens or objects that you couldn’t normally see with the naked eye. A stereo microscope on the other hand is generally used to inspect larger objects such as small mechanical pieces minerals insects and more.
