Look at the objective lens and the stage from the side (Figure 2, at right) and turn the coarse focus knob so that the objective lens moves downward (or the stage, if it moves, goes upward). Move it as far as it will go without touching the slide!
Stage Clips: Clips on the stage used to hold the microscope slide in place. On student compound microscopes many times the stage clips can be removed and replaced with a mechanical stage.
Also question is, What moves the stage up and down on a microscope?
Look at the objective lens and the stage from the side (Figure 2, at right) and turn the coarse focus knob so that the objective lens moves downward (or the stage, if it moves, goes upward).
Also, When you begin to focus your microscope the stage should be in what position? Place the microscope slide on the stage (6) and fasten it with the stage clips. Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.
Accordingly, What might happen if you lower the objective with the coarse adjustment while looking through the eyepiece? The coarse-adjustment knob is used only with the low-power objective lens, because using the coarse-adjustment knob with the higher powered objective lenses can cause damage to the lenses or slide. 3.
When can you say that the specimen is already in the right position for focusing?
A specimen that is right-side up and facing right on the microscope slide will appear upside-down and facing left when viewed through a microscope, and vice versa. Similarly, if the slide is moved left while looking through the microscope, it will appear to move right, and if moved down, it will seem to move up.
What is the definition of stage on 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 moves the stage left and right on a microscope?
Stage: The flat platform that supports the slides. … If your microscope has a mechanical stage, the slide is controlled by turning two knobs instead of having to move it manually. One knob moves the slide left and right, the other moves it forward and backward.
What is the function of stage?
The stage serves as a space for actors or performers and a focal point (the screen in cinema theaters) for the audience. As an architectural feature, the stage may consist of a platform (often raised) or series of platforms.
What are the functions of an eyepiece?
Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens. Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.
What are the two functions of the eyepiece?
Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens. Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.
What are the different parts of a microscope?

Can you use the coarse adjustment knob if your objective lens is at 100x?
DO NOT USE THE COARSE ADJUSTMENT KNOB WHEN FOCUSING UNDER THE 100X OBJECTIVE! ONLY USE THE FINE ADJUSTMENT KNOB! 6. Adjust the light for optimal viewing.
What are the functions of the base and the arm of the microscope?
Arm: Supports the tube and connects it to the base. Base: The bottom of the microscope, used for support. Illuminator: A steady light source (110 volts) 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 is the purpose of the stage adjustment knobs 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.
What happens if you use the coarse adjustment with the oil immersion objective in place?
Never use the coarse adjustment knob when focusing with the high-power or oil immersion objectives in place as this can damage the objective or the slide.
