Student Microscope how it works

A Student microscope is a low power, durable optical microscope typically sold in bulk for use in school science classes. It is also known as compound microscope or light microscope. Although university science students use microscopes, the term typically refers to the type of instrument used in primary and secondary schools. For most non-scientists, the only time a microscope was ever used was in a school science class, and so when many people picture a microscope, it is a student microscope that comes to mind.    

Amtech  manufactures a meticulous range of Student Microscopes specially designed, keeping in mind the detailed studies undertaken by the students and the rough handling done. Providing matchless mechanical and optical performance, these microscopes are value for the money invested. Amtech Student Microscopes comes in three models ST-03, ST-04 & the classic Model ST-05 .

Construction

These Student microscopes have a nose piece that is precisely para-centered and is triple revolving. For controlling the aperture, these rectangular/plain stage 120 x 120 mm microprocessors are fixed with condenser & iris diaphragm to control the aperture. Due to the cast metal body that these microprocessors are added to ensure years of high performance and adjustable down stopper to prevent damage to specimen slides and objects.

Working

A compound light microscopes work by shining a light through a condenser lens which is placed between the light source and the specimen slide. The image is then transmitted through the body tube and through the projector /objective lens and finally to the eyepiece. As the image passes through each lens it is magnified by a specific ratio, usually 5, 10 or 15X.

To use a microscope you first prepare a slide, which is a small glass plate. To prepare a slide you will place a drop of water in the center of the slide and then add the cell or organism to be viewed in the water drop. You will then use a thin piece of glass or plastic to press down the specimen and keep it in the center of your slide.

Next you will place the slide under the slide clips, which are found on the stage of the microscope. This will secure your slide. Make sure that your specimen is positioned directly over the aperture.

Now adjust the light focus of concave-plain reflector and select the objective lens that you want. Make sure your body tube is high enough so that the objective lens that you select doesn't crack or come into contact with your slide. Utilize your coarse and fine adjuster knobs to bring your specimen image into focus.

Tips for caring your Amtech Student Microscopes

• Always place the dust cover over the microscope when not in use or when being stored .
• Make sure you use both hands when carrying your microscope around. You will use one hand to support the microscope by placing it under the base of the microscope and you will use the other hand to hold the microscope by the arm.
• Clean lenses using approved lens wipes. Don't use paper towels as these can scratch the glass lenses
• Never disassemble or clean internal optical surfaces .
• Always unplug the microscope before cleaning ( models with electric illuminator )

How does the lenses in a compound microscope make the object look larger?

Can you show me the diagram that shows how compound microscopes make an object look larger.Pls show how the lenses, the light and the distance of them can contribute to the enlargement of the image of the magnified object.

Here are a couple.

The Romeros ‘invade’ Subic
Something smells over at Subic Bay. And it’s coming from a recently-signed agreement between freeport authorities and a Manila-based port operator that local leaseholders feel is going to invalidate existing contracts that they have to operate the piers and wharfs at the sprawling former US Navy facility northwest of Manila.
