Benefits of technology

This patented technology allows for improved properties such as increased visible wavelengths (visible waves) emitted from certain materials that are excited during irradiation or absorption processes. These improvements enhance their effectiveness at producing useful radiation signals like infrared rays. Additionally, this new process does away with any unwanted substances found on those surfaces being treated.

Problems solved by technology

This patented technical issue addressed in this patents relates to improving the performance of erbium-tungsten-coated fibers due to their ability to efficiently transmit visible lights over longer distances without losing them or interferring other colors like yellowish green colorants.
