Which objective should be in place both when beginning to use the microscope?
Scanning objective
Briefly describe the steps for observing a slide at low power under the compound light microscope?
Place slide on stage and stabilize w/clipsCenter slide on stageLowest-power objective lens is in placeDecrease between stage and tip of objective lensFocus with coarse and fine knobs
How do you handle and take care the microscope?
1.hold the microscope two hands one on the arm/ handle and the one is in the base of the microscope 2. Store the device in a clean dry box or cabinet, usually with some kind of plastic dust cover. 3. When using the High-Power objective lens, be very careful when focusing not to drive the head of the lens into the cover-slip or slide. Always visually adjust the head of the lens about 1 mm or so above the cover-slip, then looking through the eye-piece, use the "fine" focus control to bring the sample into sharp focus. 4. Always replace damaged parts and components with manufacture recommended replacements. If you must use other manufacture's parts, be sure they have the right specifications for your particular microscope. 5. When moving your microscope from place to place in the lab, use one hand to grip the microscope while supporting it at the base with your other hand. This keeps accidents and the lost of parts to a minimum. 6. Don't leave slide, sample, and cover-slip on the microscope stage for extended periods of time, and when through viewing, raise the objective lens away from the cover-slip and turn the objectives to the lowest power objective len setting. Remove the slide and put the microscope away. 7. If the microscope uses a light bulb as its light source, turn the power off when the microscope isn't actually in use. 8. Cleaning the eye-piece and objective lens, aways follow the manufacture's recommendations and instructions.
How to use a microscope?
1. When moving your microscope, always carry it with both hands (Figure 1, below). Grasp the arm with one hand and place the other hand under the base for support.2. Turn the revolving nosepiece so that the lowest power objective lens is "clicked" into position (This is also the shortest objective lens).3. Your microscope slide should be prepared with a coverslip or cover glass over the specimen. This will help protect the objective lenses if they touch the slide. Place the microscope slide on the stage and fasten it with the stage clips. You can push down on the back end of the stage clip to open it.4. Look at the objective lens and the stage from the side (Figure 2) 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!5. Now, look through the eyepiece and adjust the illuminator (or mirror) and diaphragm (Figure 3) for the greatest amount of light.6. Slowly turn the coarse adjustment so that the objective lens goes up (away from the slide). Continue until the image comes into focus. Use the fine adjustment, if available, for fine focusing. If you have a microscope with a moving stage, then turn the coarse knob so the stage moves downward or away from the objective lens.7. Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image.8. Now, you should be able to change to the next objective lenses with only minimal use of the focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place. Do not allow the objective lens to touch the slide!9. The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye open (this helps avoid eye strain). If you have to close one eye when looking into the microscope, it's ok. Remember, everything is upside down and backwards. When you move the slide to the right, the image goes to the left!10. Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.11. When finished, raise the tube (or lower the stage), click the low power lens into position and remove the slide.12. Always keep your microscope covered when not in use. Dust is the number 1 enemy!
Inclination joint in microscope?
An inclination joint of a microscope is where the arm of the microscope connects to the base of the microscope. Many microscopes have a pin to hold these to objects together. If the microscope is equipped with the pin you can place one hand on the base and with the other hand you can grab the arm and rotate it back and forth. The inclination joint allows the microscope to tilt back for more comfortable viewing. Please note, there is no way to contain liquid specimens if you tilt your microscope back the liquid will spill to the ground or all over.midfielder_francis@yahoo.com
A microscope should be stored with the objective in place?
It should be stored with the low-power objective in place.
Which objective should be in place both when beginning to use the microscope?
Scanning objective
Which objective lens should always be in place when beginning to use the microscope and when putting it away?
The objective lens with the lowest magnification, usually 4x. Be sure to clean all the lens with lens paper before putting the microscope away.
What holds the objective on a microscope and turns them into place?
the nosepeice. it may have other names but this is what i know it as.
Why is it not safe to remove slides from the microscope when 100x object is in place?
Because the objective touches the lens.
How you find the magnification of a microscope?
Simply, multiply the magnification of the ocular lens times the magnification of the objective lens you have in place.
What is the total magnification of the microscope when the low power objective is locked in place?
10 X 10 = 100 magnification. Ocular lens = 10 Objective lens = 10
Working principle of microscope?
microscope consists of two lens called eye lens and objective lens. objective lens is lens kept behind object and eye lens is keep on the top of microscope .i.e. on the place through which we look. firstly the object is placed behind the objective of microscope which is turned into virtual, erect and magnified image. later this image is thought to be the object for the eye lens and this objects forms real, inverted and magnified image.
When you use a microscope why do you have to put the smallest lens back into place before putting the microscope away?
Because otherwise the sample might hit one of the lenses during loading or unloading. The smallest objective lens is always further away from your sample, that makes it safer to (un)load.
Microscope problem only half the field is illuminated?
If only half your viewing field is lit, twist objective lenses until they click into place.
What is the functions of arms in microscope?
The purpose of the arm is to connect the tube to the base of the microscope. When carrying a microscope you should always have one hand holding the "arm" of the microscope and one supporting the base of the microscope.
What should be turned to click the scanning objective lens into place?
