The projector then uses a lamp or light-emitting diode (LED) light source to produce a bright beam of light. This light passes through a series of mirrors and lenses that help magnify and focus the image. The focused light is then projected onto a screen or wall, creating a larger image...

Learn about four types of telescopes. Discover what kind of telescope uses only lenses and identify wavelengths that each type of telescope can...
Whatever a user wants to look at is mounted between two glass slides and clipped beneath the main lens, and he uses a dial to focus the image. These tools use a simple series of magnifying lenses and mirrors to bring the image up to an eyepiece, much like a telescope. Compound ...
Unlike a refractor, a reflector telescope uses mirrors (that bend inward) to reflect light that has traveled down a tube, into a secondary mirror near the top of the tube directing light into the eyepiece. A reflector telescope is said to be the best value for your money, as they offer ...

Excimer laser lens provide excellent mechanical durability, high pulse count lifetime and transmission, even at deep UV wavelengths. Ultrafast lenses that possess the optimum combination of broad spectral bandwidth, minimum group velocity dispersion (GVD), low scatter, and peak pulse power damage resist...
Learn about the different types of business models through examples and insights from real businesses in ecommerce, retail, wholesale, and more.
The lens is transparent piece of glass or plastic which has a curved surface. There are two types of lenses: converging (convex lens) and diverging (concave lens). The principle behind the lens is the refraction of light.
This conversion efficiency can be increased to about 40% with the use of concentrating mirrors and lenses. This is because most of the sunlight that arrives at the cells surface passes right through it with little or no effect to the power output. ...
