Application Notes

LEDs are increasingly replacing traditional light sources in a wide range of applications. They are small, cheap, power efficient, have longer lifetimes…and the list of advantages goes on.

Efficient utilization of the UV radiation requires good measurement tools. However, accurate light measurement in this spectral range presents challenges, such as how to accurately measure the irradiance if the wavelength of the light is not known.

There are several types of wide or divergent light sources, such as LEDs or fiber optic illuminators, that can be measured with the Wide Beam Imager, but its main application is the far field measurement of VCSELs.

UV radiation is a promising approach to prevent airborne infections and infections caused by exposure to contaminated surfaces. It has long been known as an option to inactivate pathogenic microorganisms, especially for water disinfection.

Commercially available laser beam profiling products are used throughout the world to research, develop, manufacture, and test the quality of lasers and systems that use lasers. These measurement systems are also commonly employed to test and evaluate the spatial intensity distribution of other light sources.

Because of the differences in types of lights and light guides, there are great differences in uniformity of the beams emitted from the light source. This nonuniformity causes uneven curing of the resin or epoxy material, weakens that material, and shortens the life of the dental repair.

LEDs are becoming the light source of choice in many industrial, medical, and scientific applications. Correct measurement - of the right parameter - is not trivial, but is often critical to the success of the application; Ophir offers solutions specifically designed to meet them.
