What is a liquid lens?

We all drank cold soda when condensation on the side of dripping. You may notice that anything is under a drop of water is enlarged. It is a simple version of liquid lens. Water and oil are not mixed and are safe and cheap, so they are ideal for use in a liquid lens. The mixture of water and oil is inserted between two pieces of clean glass or plastic. In this way, a light, cheap liquid is created. This shape of the bubbles in the liquid lens creates enlargement and variable focus. The oil component of the liquid lens is filled in the rest of the space to prevent the water from cheating.

Any gadget that requires a small, lightweight lens can benefit from using the UID lenses. Mobile phone cameras, small digital cameras and many other types of consumer electronics use liquid lens technology not only because of weight and cost savings, but also because water naturally creates a flawless lens. The same wayBem, such as the human eye lens, changes the focus of its shape, the liquid lens is also able to change the focus. By changing the size and shape of a drop of water in a liquid lens, the camera can change the focal length. This would be more difficult with a standard lens, because the lens cannot change its shape and therefore must be physically moved to change the focus.

liquid lens technology has a wide range of applications. Because the liquid lens is so small, light and cheap, it can be easily integrated into various objects. Soon every laptop can come with a built -in web camera made of liquid lens. One of the few disadvantages of liquid lenses made of water is that it is subject to freezing at low thermal. If you have a mobile phone or a camera with a liquid lens, be careful not to expose it to very low temperatures for a long time, or you can damage the liquid by freezing the water inside.
