What is a microscope and how does it work?
A microscope is an instrument that can be used to observe small objects, even cells.
The image of an object is magnified through at least one lens in the microscope.
This lens bends light toward the eye and makes an object appear larger than it actually is..
What is the microscope base?
Base: The bottom of the microscope, used for support. Illuminator: A steady light source (110v) used in place of a mirror. If your microscope has a mirror, it is used to reflect light from an external light source up through the bottom of the stage.
What are the 3 types of objectives in a microscope?
Most compound microscopes come with interchangeable lenses known as objective lenses. Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and(typically) oil immersion objectives, respectively.
What should you never allow the slide to touch?
6. Why should you never allow an objective lens to touch the slide? The lenses and slides are very delicate and can be damaged easily if allowed to touch.
What activity might lead to damage of a microscope and specimen?
Which activity might lead to damage of a microscope and specimen? using the course adjustment to focus the specimen under high power. While viewing a specimen under high power of a compound light microscope, a student noticed that the specimen was out of focus.

What each part of a microscope does?
Eyepiece Lens: the lens at the top that you look through, usually 10x or 15x power. Tube: Connects the eyepiece to the objective lenses. Arm: Supports the tube and connects it to the base. Base: The bottom of the microscope, used for support.
Why can’t I see anything through my microscope?
The sample is of too low concentration: This means that you are only observing a clear liquid without many cells or other particles. As a general rule of thumb, if you are able to see through the sample without any problems, then you will also not be able to see anything under the microscope.
What does the stage control do on a microscope?
Stage height adjustment (Stage Control): These knobs move the stage left and right or up and down. Aperture: The hole in the middle of the stage that allows light from the illuminator to reach the specimen. On/off switch: This switch on the base of the microscope turns the illuminator off and on.

Why should microscope lenses not be touched?
Never touch the eyepiece or objective lens with your fingers because the oil on your skin will soil the lens. … Dust is an enemy to your lenses, hence when finished; the microscope must be covered with a plastic cover again to keep out dust.
Where is the stage located on a microscope?
The stage of a microscope is the aluminum or iron platform where the specimen, usually on a glass slide, is raised or lowered for observation under the microscope. Microscope stages will often include stage clips that will hold the slide in place while the stage is being adjusted up and down or side to side.

Are all three threads in focus at 40x?
Notice that all three threads are fairly well in focus, although the white thread on the bottom is a bit blurry. At low magnification, things appear bright, and it is easy to bring them into focus. Once you have explored the threads at 40X, switch to a higher powered objective.
