[David Prutchi] has just shared his incredible work on making his own shortwave ultraviolet viewers for imaging entirely outside of the normal visible spectrum – in other words, seeing the truly ...

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.

This includes the ultraviolet (UV) band around 300 nm, especially if short pulse durations and/or high intensities are needed.

According to Schlesinger, iron oxide used in tinted sunscreens can protect a large portion of the visible light spectrum, all the way up to 700 nm, including blue light.

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 ...

IMM Photonics presents a newly developed LED featuring a continuous spectrum from 400 nm to 750 nm. Due to their internal design, standard white LEDs have a gap in the spectrum between 400 nm and 450 ...

The TM series mini-spectrometers from Hamamatsu are polychromators that feature an image sensor, a driver circuit, and optical elements. Through an optical fiber, light is directed into the entry port ...
