Microscope Magnification
The world is an interesting place, but it's fascinating up close. Through the lens of a microscope you can find details that you would otherwise never notice. But now you can. This instructable will show you how to build a stand for about $10 that will transform your smartphone into a powerful digital microscope. This DIY conversion stand is more than capable of functioning in an actual laboratory setting.
With magnification levels as high as 175x 375x Edit: with the addition of a second lens magnification can be as high as 375x, plant cells and their nuclei are easily observed! In addition to allowing the observation of cells, this setup also produces stunning macro photography. Free Oxford Handbook Of General Practice 3rd Edition.
The photos in this instructable were taken with an iPhone 4S. Watch the video below for a quick overview of the project! The cost of this project is just $10 (not counting the smartphone), and it only takes about 20 minutes to build. You can be viewing cells with your smartphone within the hour! The focus lens of just about any laser pointer will act as the macro lens on the microscope stand. Don't waste money on an expensive model; the lens from the $2 laser is fine.
EDIT: To achieve higher magnification (up to 375x), use a second lens! To get the lens from the laser pointer start by unscrewing the front cone and the back cover of the tube. Remove the batteries. Using the eraser end of a pencil, push the innards out of the front of the tube.
Magnification in physical terms is defined as 'a measure of the ability of a lens or other optical instruments to magnify, expressed as the ratio of the size of the image to that of the object'. This means, that an object of any size is magnified to form an enlarged image. The magnification required to produce the. A Foldscope is an optical microscope that can be assembled from simple components, including a sheet of paper and a lens. It was developed by Manu Prakash and. The Concept of Magnification. A simple microscope or magnifying glass (lens) produces an image of the object upon which the microscope or magnifying glass is focused. Simple magnifier lenses are bi-convex, meaning they are thicker at the center than at the periphery as illustrated with the magnifier in Figure 1.
Ram Amritwani By Anuradha Paudwal Download. The front of this assembly (the side without the spring to contact the batteries) is where the focus lens sits. Unscrew the small black piece of plastic in front of the lens and the lens will come free. Step 3: A Few Notes on the Lens. The lens, when viewed from the side is not symmetrical. You’ll see a thin translucent strip (~1mm) on one side of the lens. That side must not be adjacent to the camera. You can determine the correct orientation by sticking the lens between the prongs of a hairpin and taping the rig to the back of a smartphone.
The correct orientation will provide you with a larger field of view. As it is, you can take reasonably good macro photos with this lens and smartphone. This simple rig is limited; not to mention, it’s extremely hard to keep the phone steady when taking zoomed in photos. That’s why we need to build a stand! Step 4: Drilling the Bolt Holes.
