Mechanical wire wrap tool Electrical wire wrap tool; pneumatic (air-powered) tools are also available. A "wire wrap tool" has two holes. The wire and 1 ⁄ 4 in (6.4 mm) of insulated wire are placed in a hole near the edge of the tool. The hole in the center of the tool is placed over the post. The tool is rapidly twisted.
A very complex dielectric mirror can reflect up to 99.999% of the light incident upon it, for a narrow range of wavelengths and angles. A simpler mirror may reflect 99.9% of the light, but may cover a broader range of wavelengths. Almost any dielectric material can act as a perfect mirror through total internal reflection. This effect only ...
The rays represent luminous intensity, which varies according to Lambert's cosine law for an ideal diffuse reflector. Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection .
In the early 10th century, the Persian scientist al-Razi described ways of silvering and gilding in a book on alchemy, [citation needed] but this was not done for the purpose of making mirrors. Tin-coated mirrors were first made in Europe in the 15th century. The thin tinfoil used to silver mirrors was known as "tain". [5]
A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat reflective surfaces. It reflects waves incident from any direction directly towards the source, but translated .
A bicycle reflector or prism reflector is a common safety device found on the rear, front and wheels of bicycles. It uses the principle of retroreflection to alert another road user of the bicycle's presence on the road. The reflector is usually manufactured in the form of a moulded tile of transparent plastic.
Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser .
