Another important application for UV lasers is wafer inspection ... He pointed out that cutting LED wafers with YAG lasers at longer wavelengths produces burning around the edge of the cut.

The entire wavelength range of the UV product series is covered in incremental steps from 5 nm to 25 nm. The company’s two newest UV LED devices operate at 225 nm and 230 nm, respectively ...

as [Markus Bindhammer] shows with this proof-of-concept UV/visible spectrometer. Rather than a single light source, [Marb] uses six discrete LEDs, each with a different wavelength. The almost-a ...
