A microscope composite light microscope is an optical tool used by students and scientists to amplify very small objects or details.
However, the most commonly used microscope type for students is the basic composite optical microscope.
This microscope is called a \"composite microscope\" because it uses two lenses to amplify objects on the slide.
The composite optical microscope is suitable for examination of cell, biological and inorganic materials.
A composite microscope is needed for many science expo projects.
The composite light microscope glows by a condenser lens placed between the light source and the sample tray.
The image is then transmitted through the body tube and the projector lens, and finally to the eyepiece.
When the image passes through each lens, it is enlarged by a specific scale, usually 5, 10, or 15 x.
To use a microscope, you prepare a slide first, a small glass plate.
To prepare the slides, you will place a drop of water in the center of the slides, and then add the cells or organisms to watch in the drops.
You will then press down the specimen using a thin piece of glass or plastic and keep it at the center of the slide.
Next, you will place the slides under the slide clip on the microscope stage.
This will protect your slides.
Make sure your sample is located directly on the aperture.
Now you will turn on the light source and select the objective lens you need.
Make sure your body tube is high enough so that the objective lens of your choice does not break or touch the slide.
Focus the sample image with a rough and fine regulator knob.
Another option for oil immersion lenses is to use the oil immersion lens process, which is another option for you to show details in an organism or sample.
In the process, you will create a wet installation slide as before.
You will then move the objective lens so that there will be no capture of any lens to capture the location.
Next, you will put a small drop of oil on the cover.
You will then capture the 100X objective lens in place, which will make it in contact with the oil.
Use the fine-tuning knob to lift the lens about 1mm from the slide cover.
Next, continue to adjust the fine-tuning knob until the image is focused.
Components of the microscope: the arm of the microscope is a projection in the shape of a metal or plastic handle connecting the nose sheet/body tube structure, and it also acts as the handle of the microscope.
Body Tube: body tube is a container for objective lenses that hold enlarged sample images.
An eyepiece was placed on the top of the body tube.
Coarse Knob: the heading adjustment knob can be found on the side of the microscope.
You can use this knob to focus on the enlarged image.
This knob focuses the image by moving the body tube/nose part configuration up and down.
Diaphragm: The diaphragm is a device used to control how much light is allowed through the aperture or through the hole on the stage.
EYE Film: Eye film is the entrance to the image, and also the place where you look at the image on the slide.
Fine-tuning knob: fine-tuning knob is also available on the side of the microscope.
However, this knob is used to fine-tune the focus of the sample image.
Light Source: The light source can be found at the bottom of the microscope.
Most student microscopy will have an electric light as a light source, however, there are also some more basic models that use mirrors to capture and focus light from an external light source through an aperture.
Nasal film: the nasal film was found at the bottom of the body tube.
You can operate this part to select an objective lens magnification of your interest.
Objective lens: objective lens is tube-
Like the lens head found at the bottom of the body tube.
Each lens has a specified specific amplification power, such as 5, 10, or 15 Xs amplification.
To select the magnification you want, turn the nose part that rotates the objective lens of your choice to the view position.
Stage: The stage of the microscope is a flat platform suspended between the light source and the objective lens.
There is a hole in the center of the stage where the light passes through, which is called the aperture.
There are also two clips on the stage that you can use to hold the slides to the stage.
Tips for nursing the microscope make sure you use both hands while carrying the microscope.
You will support the microscope with one hand by placing the microscope at the bottom of the microscope, and you will hold the microscope with the other hand with the arm.
Avoid shaking or shaking the microscope.
This can damage the internal components of the microscope and damage the alignment of the lens.
Make sure you always place the microscope on a solid surface at least 3 inch from the edge of the surface.
This will prevent it from falling off the surface, and it will also prevent people on your science class from walking out of date to catch clothes.
Clean the lenses with approved lenses.
Do not use paper towels as they scratch glass lenses.
Do not force the regulator knob.
If they get stuck, check their location and make sure they don\'t lean on the slide.
Student School lab home school microscope what kind of microscope do you need?
A high power or composite microscope magnifies the thin sample portion mounted on the slide.
They are ideal for observing tiny substances that are not visible to tissues, cells, protozoans and other human eyes.
Most families in family schools need this microscope.
The low-power microscope has a typical magnification of 10 to 40 times and is widely used.
These microscopes are designed to observe the entire object such as rocks, insects, and flowers, but can also be used to observe prepared slides.
They are very helpful for students in natural science and especially ideal for young children, as slides can be viewed without stress.
Consider a low-power microscope as an option for 2nd, or as a microscope for 2nd, as it does not meet the high school biological needs you have to look at the details of the cells.
No microscope can do low power and high power at the same time.
Now technology gives us more choices.
You can get a twelve mirror.
Duoscopes allows you to view slide samples as well as 3D objects such as flowers, rocks, leaves, etc.
These microscopes have become a favorite for young scientists and amateurs.
See images in this section.
The digital/video eyepiece is mounted in the lens of the microscope so you can view the specimen on a TV or computer screen!
Tips for using a microscope when using a microscope you have several slide making options.
If it\'s hard for you to see the details of the sample, try other slide-making techniques such as dry slides, wet slides and oil-soaked slides.
If you have long hair, pull it back into a ponytail or clip.
This will prevent loose hair threads from covering your field of vision and will also help prevent your hair from polluting or interfering with the slides you have prepared.
