Solar radiation in the 240 nm to 280 nm range is completely absorbed by the ozone in the atmosphere and cannot ... The only problem with examining the UV spectrum with a small camera is that ...

Dr. Brenner and his team hypothesized that a very narrow spectrum of UV light -- around 207 nm -- might be capable of destroying bacteria while leaving human tissue unaffected.

By contrast, far-UVC light (207–222 nm) efficiently inactivates bacteria without harm to exposed mammalian skin. Far UVC is simply a short wavelength part of the ultraviolet spectrum. ...

But researchers from Columbia University Medical Center have found that a narrow spectrum of UV light — at 207 nm — can kill bacteria like methicillin-resistant S. aureus (MRSA) while leaving ...

With new technologies, lasers cover a growing spectrum, but some wavelengths are still not easily accessible. This includes the ultraviolet (UV) band around 300 nm, especially if short pulse ...

Your question in the visible spectrum would be is there some way to convert red photons (625-740 nm; 1.65-2.00 eV) into shorter wavelength higher energy orange photons (590-625 nm ; 2.00-2.10 eV ).

The current sunscreens offered in the U.S., Schlesinger explained, do not protect all the way to the end of the UV spectrum, including visible light, with the exception of tinted sunscreens.

Highly Sensitive UV to Near IR (200 to 800 nm) Mini-Spectrometer – Hamamatsu TM Series ... and the spectrum measured with the integrated image sensor is sent as from the USB port to a PC for data ...

Dr. Brenner and his team hypothesized that a very narrow spectrum of UV light—around 207 nm—might be capable of destroying bacteria while leaving human tissue unaffected.
