Within the germicidal UVC range, 260 nm to 270 nm is seen as an ideal wavelength, with only a small drop in efficacy in damage to the nucleic acid across that wavelength range (peak DNA/RNA absorption is observed between 263 nm to 265 nm) while, outside that range, the efficacy of longer or shorter wavelengths starts to fall drastically.

As is obvious, there is a dramatic drop in UV transmission of this material below 265 nm. This is one of the reasons so many scientists have difficulty with UV microspectroscopy between 200 to 265 nm when not using CRAIC quartz wellslides. The red line represents the optical grade quartz used by CRAIC Technologies in their quartz wellslides.

    Oct 01, 2011 · The effectiveness of the UV wavelengths depends on the DNA absorption curve. The absorption peaks between 260 nm and 265 nm, which makes this range the most efficient for inactivation / disinfection. DNA, however, absorbs UV in the whole wavelength range between 200 nm and 315 nm, so any light emitted in that part of the

    UV radiometers provide the quantitative measurement of light sources emitting electromagnetic radiation in the wavelength range of 100-400 nm. UV radiation is divided into three separate wavelength ranges: UV-A (315-400 nm), UV-B (280-315 nm) and UV-C, or germicidal UV (100-280 nm) with peak effectiveness in the 265-270 nm range.

    The LEDs of the PLS Series are the only available compact pulsed light sources that emit directly in the ultraviolet spectral range at wavelengths as short as 255 nm. Eight different LEDs with central wavelengths between 255 nm and 370 nm allow to choose a peak wavelength according to the needs of the application.

    May 18, 2016 · The present results showed that sensitivities to 600-nm light were remarkably lower than those to 532-, 546-, and 570-nm light. This result potentially reflects peak absorption spectra (λ max values) of opsin proteins in guppy photoreceptor cells. Accordingly, 600-nm light is mainly absorbed by LWS-1 opsin (λ max, 562 or 571 nm).

Jun 10, 2020 · I have had a 24 5mm LED 395 nm-ish UV flashlight for a few months. Cheap as chips and it worked for finding scorpions. It puts out a lot of visible purple light. Yesterday I received my Nailbender P60 dropin with 365 nm Nichia UV led hosted in a 6P with stainless bezel and McClicky (I’m sure the previous owner is on this forum somewhere!).
Light wavelengths between 100 and 400 nm are considered ultraviolet (UV). Wavelengths below 100 nm are extremely hazardous (i.e.; ionizing radiation such as gamma rays and X-rays). Beyond 800 nm, the radiation is in the form of infrared (or heat rays), microwaves and radio waves.
