Light Sources

Light is a type of electromagnetic radiation. It is categorized by the length of lightwaves. Not all light can be seen by humans due to the structure of our eyes. It has been a significant part of our lives throughout the ages, and creating artificial sources of light is considered one of the greatest achievements that pushed forward the technological process.

Light is necessary for us to see objects, therefore to work. General sources of light, like flashlights and lamps, are installed and used inside buildings as well as to light outside areas, like pavements, roads, or any objects of significant importance. Light is also utilized in examining equipment, structures, and areas of interest. Industrial lights and specialized flashlights were created for such purposes. These gadgets emit light of high intensity, and batteries that power such light sources have greater capacities than normal batteries.

We offer a great selection of light sources from AFS, Wilcom, and more. Shop with Mega Depot!

Special optical fiber has been invented not a long time ago. It is used in cables and wires to transport information across large distances. It is essentially an extremely thin thread of glass. The cable with such material does not experience energy losses like metal wires do. The major improvement of optical fiber is that it’s not affected by any electromagnetic interference. But since optical fiber operates with different types of signals, they require special equipment for maintenance and repair. Specialized light sources are used to test such optical fiber cables. They emit light with a wavelength we cannot see and transfer the signal along the cable, measuring the amount of time the signal travels and other parameters required for performing an examination. These light sources can adjust the wavelength of light they emit, so they can be used with different types of cables and perform various types of tests.
