7511A55

Optics is the branch of science that studies the behavior and properties of light and its interaction with matter. Light pipes are engineered devices that guide light from an emitter to an end user. The 7511A55 is a type of light pipe which has a specific application field and working principle.

The 7511A55 is a cylindrical light pipe used for point-of-sale (POS) applications. It can be used as a thin, long bar within a POS terminal to direct light from the system\'s main lightsource to the bar code scanner. It is made of two molded components, a plastic cylinder and a flat, reflector-like surface inside it, which directs the incoming light from the end emitting the light out its opposing end. The cylinder has near-perfect internal reflectance properties, which allow it to efficiently convey light from the source to the intended target.

The advantages this type of light pipe offers included its ability to guide the light around obstructions like metal or other high-density materials. It can also be used in tight spaces and in applications involving curved surfaces. Furthermore, the 7511A55 has a wide acceptance angle, allowing for more precise and accurate light guidance and distribution.

The 7511A55 is designed for applications such as identifying bar codes on retail items, reading small fonts and scanning documents. Its light guidance capability can also be used to differentiate between various types of items, such as cigarettes, tobacco and electronic products, which makes the 7511A55 particularly useful in retail applications. It also offers a higher level of accuracy, allowing for faster scanning and a more accurate system.

The working principle of the 7511A55 is based on total internal reflection (TIR). Light enters the cylinder through its end emitting light, and is reflected off the walls of the cylinder in a direction parallel to the cylinder\'s axis. The reflector-like surface gives the light a slightly divergent output, allowing it to spread out over a wider area at the end where the light is collected. The rotation of the cylinder allows the light source to be positioned at the optimum angle for the best light distribution.

The 7511A55 is a highly efficient light guiding device that is normally used in point-of-sale (POS) applications. Its ability to deduce and sense bar codes on small items makes it an ideal solution to this type of need. Its TIR-based GUIDance also makes it very efficient in tight spaces and curved surfaces. The 7511A55 is an efficient and reliable light pipe that is suitable for a wide range of applications, making it an attractive solution for many businesses.
