What other cunning things can you do to change the way your lens works? Like all great scientists, take the chance to play around and experiment. Ice lenses Does it seem strange to make a lens out of (liquid) water? Would you be so surprised if the lens were made from (solid) ice?
So how does laser eye surgery actually work? The first step is to separate a thin layer from the front of the cornea. This can be done with either a flat, wide blade, or a femto-second laser that produces millions o...
The lens, which would be classified a "plus" lens because it is thickest toward the center, and the cornea work together to focus the image onto the retina. (For more information on how the eye functions, see How Vision Works.) Definitions Aberrations: ghost images, halos, waves or ...
How does a Barlow lens work? Simply put, a Barlow lens increases the effective focal length of the telescope. It does this by diverging light before it enters the eyepiece, which increases the magnification of the image. A Barlow Lens can double the magnification of your view. However, the ...

you to digitize physical documents, images, or even objects, and convert them into a digital format that can be viewed, edited, and stored on a computer. it's like a digital photocopier that captures the content of a document or image and saves it as a file. how does a scanner work?
How Does a Microscope Work ?A great deal of optical science is involved in answering the question "how does a microscope work?" A simple microscope has one lens and is essentially a loupe or magnifying glass with a relatively high magnification....
Lenses: Holography is often referred to as "lensless photography," but holography does require lenses. However, a camera's lens focuses light, while the lenses used in holography cause the beam to spread out. A beam splitter: This is a device that uses mirrors and prisms to split one beam...
