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
Why do you place one hand under the base of the microscope as you carry it?
You place one hand under the base of the microscope to distribute the weight and not cause damage to the neck of the microscope where important pieces are. It also helps so you don't drop it, two hands are better than one.
A microscope should be stored with the objective in place?
Yes, it is recommended to store a microscope with the objective lens in place to prevent dust or debris from entering the lens threads and affecting the performance of the microscope. Additionally, storing the objective in place helps maintain the alignment and calibration of the microscope for accurate observations.
What should objective lens should a microscope be stored in?
A microscope should be stored with the lowest-power objective lens in place to prevent damage to the higher-power lenses. It is recommended to keep the 4x or 10x objective lens in place for storage as they are less delicate than the higher magnification lenses.
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 power must be in place when you first find an image in the microscope?
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
Why a microscope should be stored in low power objective lens?
Storing a microscope with the low power objective lens in place helps protect the lens and prevents accidental damage or contamination during storage. The low power lens is less delicate compared to other high-power lenses, making it a safer option for storage to ensure the microscope remains in good condition for future use.
To observe a skin cell through a microscope at highest magnification you should first?
To observe a skin cell at the highest magnification through a microscope, you should first place the skin cell slide on the microscope stage, focus the microscope using the coarse and fine focus knobs, adjust the light intensity, and then increase the magnification to the highest level possible on the microscope objective.
What part of the microscope holds the objective lenses and rotates the objective lenses?
The revolving nosepiece holds the objective lenses and allows them to be rotated into place for viewing different magnifications.
What power must be in first place a slide on a microscope stage?
The lowest power objective lens should be in place when placing a slide on a microscope stage. This allows for easier focusing and initial viewing of the specimen at a lower magnification before switching to higher magnifications.
What holds the objective lenses on a microscope?
The objective lenses on a microscope are held in place by the revolving nosepiece. This rotating mechanism allows users to easily switch between different objective lenses to adjust the magnification level.
How is magnification controlled in a microscope.?
by the objective lens
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.
What part of the microscope supports the objective lens system and the eyepiece?
The body tube of a microscope supports the objective lens system and the eyepiece. This tube holds the optics in place and allows for adjustments to focus on the specimen.
