Learn The Best Ways To Use A Compound Light Microscope
What is a compound light microscope? It is a laboratory tool utilized for a variety of purposes. It is common knowledge that it can be very complex. Proper knowledge on the best ways to use a compound light microscope will not only help you use it to its fullest but will also allow you to enjoy the experience.
Light: The Ultimate Source
A compound light microscope makes use of light to view an object. It can come from a self-illuminating item or a mirror. When the light passes through the objective lens, it creates a bigger image of the object. The eyepiece, meanwhile, functions as its magnifier, which can produce a much bigger version of the image from the objective lens.
To determine the magnification, just multiply the magnification of the eyepiece by the objective lens’s magnification. A 10x magnification of the eyepiece multiplied to the 40x magnification of the objective lens can produce a 400 magnification factor. A compound light microscope has a magnification limit of 2000x. Otherwise, the image will be unidentifiable.
Proper Care for the Microscope
Not only is a microscope complicated, it is also very delicate. Thus, proper care should be extended especially in transporting it. The best way is to hold it with your arms. Components that attach the base and the nosepiece should be held by one hand, and the other hand should support the base. When you’re not using the instrument, you have to cover it or better yet placed in a Styrofoam packaging, especially if it’s going to be stored for a long time. Avoid having contact with the surface of the lens. This is because hands can be oily, and it can create stains or scratches. For lens cleaning, use a lens paper or lens cleaner. For the rest of the instrument’s surfaces, you can make use of a damp cloth. Nevertheless, for periodic maintenance, always seek professional help.
How to Place a Microscope
The compound light microscope should be placed on top of a secure table, one that’s void of any vibration. To prevent any accidental fall, the instrument should be placed at least 1 foot from the edge. You can then power on its illumination or, if it’s using a mirror, focus the microscope to the best light source, then tilt its mirror until you can get the best view of the object under scrutiny.
How to Enjoy Viewing
To fully enjoy the experience of viewing organisms under a microscope, you must learn how to look at them with no closed eyes. You can practice it by covering one of your eyes with one hand. At first, it may seem to be hard, but later on, you’ll learn to get used to it.
Handle Objectives Properly
You can rotate the nosepiece or the turret if you want to choose the best objective for the kind of magnification you require. Your goal is to align both the nosepiece or turret to the eyepiece. You will know that what you did was right if you hear a clicking sound.
Put the slide on the microscope’s stage. Secure it by using stage clips or mechanical stage, whenever available. To easily view the specimen under an eyepiece, it must be situated at the center where its objective will normally come down. Before you begin looking into the eyepiece you must lower down the objective by turning the compound light microscope’s coarse focus knob until the slide and objective will be almost in contact. This is because if you will look into an eyepiece and then the objective is moved downward, there’s a tendency of contacting both the objective and slide, damaging either or both of them.
Start from the Basics
One of the best ways to use a compound light microscope is to start from the very beginning. Study simple specimens first before moving into complicated ones. Don’t get too frustrated if it doesn’t come out right at first. You can ask for assistance from a professional, like a lab technician or a biology professor, for some ideas on how to effectively use the instrument.
