Customized 2.5 m long LED illumination provides the right light for micrometer-precise cell distance measurement in solar modules.

The Ferdinand Braun Institute has fabricated micro light-emitting diodes in the UV spectral range. The tiny LEDs can be densely packed to form high-resolution arrays.

New device produces a bright, warm light with even less blue wavelength emissions than natural candlelight.

Replacing standard lighting with UV-LED lights could be a powerful tool in stopping the spread of Covid-19.
