You’ve probably heard the word optics before. The optician in the retail world is the one who sells the glasses. And these glasses are also a part of the optics. The word originally comes from the ancient Greeks and means "the science of seeing". That's what makes optics so interesting. You can see it everywhere around you. And being able to see is something we owe to the world of optics. Without the lenses in your eyes, you would just be able to tell whether something was light or dark. But you wouldn't be able to tell what it is or even see sharply.
People have been thinking about seeing for quite a long time--especially anyone with bad, or blurred vision that has been bothering them. And so about 700 years ago someone first invented glasses and magnifying glasses, which could correct optical defects of the human eye with the help of glass lenses. And that is exactly what we do. We don’t have to invent the magnifying glass, it already exists. But we can rebuild it.
Hundreds of years ago, people already wondered how they could see the world differently through a drop of water or a glass of water. Have you ever noticed that a spoon in a glass of water looks as if it was broken just below the surface of the water? This is due to the refraction of light. The light is slightly deflected (refracted) at the surface of the water. This always happens with light when it hits a transparent material that has a different density. The same thing occurs when light moves from air to water; or in the case of a lens, from air to glass and back to air.
Try 1: Everything is upside down?!
Try 2: The focal length - what is that actually?
Experiment 3: Calculating the magnification with the Smart SuperZoom
The length of the distance on the display divided by the length of the distance as shown on the paper gives the magnification factor.
Try 4: Smart SuperZoom - How it works
The lens in your Smart SuperZoom reduces the focal length of your phone's camera. This means that the camera can be moved closer to the subject while keeping the image on the phone screen sharp. Using the digital zoom of your smartphone, you can also zoom in on the subject. The magnification depends on the camera and the display size of your smartphone. Depending on the model, up to 26x magnification is possible. To get a sharp image on your Smartphone display, it is important to keep a working distance of 25 mm between the Smart SuperZoom lens and the object to be viewed. On the Smart SuperZoom, this is ensured by the three legs.
The accessory PLUS LED Set, part #533877 (sold separately) is the perfect addition to your Smart SuperZoom. With it you can illuminate the observed objects and depending on the object, very interesting images are created, e.g. of slightly uneven objects such as fabric, stones, wood, coins, etc.
