How to build a microscope with your own hands: an instruction for manufacturing

Before you make a microscope with your own hands, you need to understand what it can be used for, and what materials will be needed for this. It should be noted immediately that you can build such a structure yourself, but you do not need any expensive items.

What is the device used for?

In principle, the main goal of any microscope is to increase the object by a few tens or hundreds of times. Applied devices are used not only in biology lessons at school, but also in medicine, electronics and other fields. For example, thanks to a digital microscope, it is possible to repair very small microcircuits, mobile and computer cards.

The most convenient is an electronic device, since it is capable of increasing the object very much. It should be noted that it is not difficult to build a microscope by oneself. You just need to know its device, and also collect the necessary materials.

What can a device be made of?

Naturally, you can design a microscope with your own hands and from scratch. However, often those people who understand electronics, computer technology and optics, make the presented device on the basis of other units: cameras, binoculars, web cameras.

Before you start making a design, you need to accurately determine its functions, pick the right elements. It is also desirable to draw a drawing of the device on paper. Naturally, all necessary calculations are made.

We make the machine from scratch: the necessary materials and tools

In order to make a microscope with your own hands without ready-made instruments, you will need such equipment:

- A tube of glass. Its length should be about 20 cm, and the diameter - up to 6 mm.

- Several plates (preferably of copper). The thickness of the metal should not be large (about 1 mm). As for the overall dimensions of the plates, they are 3 * 6 cm.

"A few small glasses."

- Drill of small diameter.

- Gas-burner.

- A hammer.

- Screwdriver.

- Nuts and cogs.

If you do not have metal, which will serve as the basis for the design, you can use a thick cardboard. However, note that in this case the device will not be strong and will not last a long time.

We make the device: the instruction

Before you make a microscope, review the sequence of the work:

1. First of all, from a glass tube with the help of a burner it is necessary to make a small ball, which will serve as a lens for the device. Please note that this element should not be touched by hands in any case, since there will be traces on the surface that will later distort the image.

2. At this stage, you need to make a lens housing. For this you need metal plates. To use this device was convenient and safe, you must necessarily round the corners. In the "body" should drill holes: 4 fasteners and one lookout.

3. Now you can assemble the whole structure together. For this purpose, a "lens" is installed between the plates, and the body is bolted together. Further on one side of the lens with the help of adhesive tape can be glued glass, which will fit the object.

This microscope design is manual and simple. The presented device can be used by adults at home and children. For professional work you will need a more sophisticated, digital apparatus. Next, you will learn how to build it.

How to make an electron microscope: the necessary materials

To produce the presented device, a webcam is usually used. Before you make a microscope of this type, collect all the necessary material and tools:

- Personal computer or laptop.

- Web camera (preferably with manual focus adjustment). Please note that we will need a lens, so it must be easily removed from the original device.

- Several large and small corners, from which a post will be built later.

- A steel tube of small diameter and a special fastening that can move and fix on the surface of the metal.

- Glass.

- A small mirror or flash from a mobile phone to design the backlight.

- Metal plate for making the platform.

- Fasteners, as well as a hotmelt gun.

Instructions for manufacturing a digital microscope

A digital microscope with its own hands is done very simply, you only need to follow a certain sequence of actions:

1. To begin with, you must build a "skeleton" of the structure. To do this, connect the metal plate to the corners. All elements can be bolted. A small diameter metal tube can be used as a tripod. It has certain advantages. For example, with special fasteners, you can fasten another small piece of pipe to the vertical element, to which the lens will attach. If necessary, you can raise or lower this element. In addition, for the construction of the platform, you can also use a small cardboard box into which a tripod is inserted and filled with tile (or other) glue. Please note that the design should be as stable as possible.

2. Next, you can make the focus adjustment knob. For this, a nylon thread (or elastic band) is used, a movable bushing, a tab for fixing the thread on the tripod. That is, you need to make a kind of reducer, thanks to which the accuracy of the focus of the lens increases.

3. The electron microscope is then made simply by hand. Now, unscrew the lens from the webcam. Do this carefully so as not to damage the element. Then you need to turn it around and put it in its place. For fixing, use hot melt. The finished structure can be attached to the movable part of the tripod. Under it should be organized a stage with backlight. For this, a conventional LED is used.

4. Lastly, you need to process the webcam's wire. That is, you should cut off his thick braid. In this case, it will become more flexible and will not interfere with the movement of the lens.

Now you know how to make a microscope with your own hands. Good luck!
