remember school biology lessons, in which we examined the cells dyed with iodine onion under a microscope?What then seemed mysterious insight into this mysterious invisible world!
turns out to each of us the strength to make a real microscope of webcams with their own hands.You do not need special skills, just a few items that exist in any home.This webcam we do not spoiled, it can work as well as worked before.So, we need:
• USB webcam;
• adhesive tape;
• scissors;
• Front (rod fastened to the base of the vertical), can operate as a stand;
• the stage on which we lay our future research facilities;
• lights - any source of light bright enough, you can even use a flashlight mobile phone.
Let's start!The first step - the conversion of the camera into a microscope.To do this, simply unscrew the lens and insert it back, but the other party.It turns out a stunning effect of the increase.Well, if the camera for the microscope even megapixel.You can take less, but the magnification, respectively, will also be less.
next step - a tripod.The more stable it is, the easier it will be to set up a microscope from a webcam.It is best to choose a rigid rod, which should be strengthened at the edge of a base of sufficient size, with a party of about 20.
centimeters on a tripod at a height of about 10 cm make the stage the size of a pack of cigarettes.At its center is necessary to make a hole for illumination from below.For a table suitable thick cardboard, which is easily fixed to a tripod using the L-shaped bracket and adhesive tape.Corner can be ready to take or cut a thin tin, such as tin.
remains mounted on a tripod, actually, a microscope from a webcam.Note that the lens should be free to approach the subject of only a few millimeters, so if the shape of the front part of the body does not allow it, then it must be removed.Webcam microscope attached by analogy with the stage, but not to the tripod, and a ballpoint pen or something similar.And after that the handle is fixed on a tripod so as to be able to push it up or down a couple of centimeters to adjust the focus.Secure can be a thin copper wire.
Our microscope of the webcam is almost ready.Now you are sure to light up the stage at the bottom.If you do not find anything suitable, use a small mirror.Arrange it under the table at an angle so that it will cast a light spot from the light source on the sample stage.The light source can be a table lamp or a flashlight.
now need to focus the camera.Connect it.On the stage, place a sheet of paper with printed text and moving the webcam at our makeshift sled, adjust sharpness.Now that you know the approximate focal length.Here is a new application was received by our webcam.The microscope is ready for operation.
Of course, the design is not ideal, and it is made in haste.If you're addicted, you probably come up with a far superior version of it.Successful experiments you!
