Is it for water disinfection and decontamination purposes? For disinfection and decontamination (240 nm – 280 nm) spectral range is suitable , so 250 nm is better

Rainer Kling

Thank you. We built UV modules for water disinfection and decontamination

Most feasible would be a tunable UV Source from 200 -280nm

Arie Shapira

How much power would you need at the output?

generally LEDs at these wavelength are less powerful.

also, would you want that fiber coupled or collimated or free?
