For example if bacteria received a dose of 32 J/cm2 of irradiation in 9 minutes from a LED light source would it mean that they received a dose of 32 w/cm2 in 9 minutes. At 600 nm, exposure of more than 3000 J/cm2 did not cause funduscopic damage. UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. The latter is commonly measured in J⋅m −2 ⋅nm −1. 1 mW/cm2 = 10 J/; 1 J/ = 0.1 mW/cm2. Note: Fractional results are rounded to the nearest 1/64. However, the use of UV skin blocks is considered inadequate for protection against the high irradiance of man-made UV radiation sources. Co-enseignement en mathématiques l’après-midi. Data should be separated in coma (,), space ( ), tab, or in separated lines. The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. This threshold dose for funduscopic damage increased monotonically from 0.35 J/cm2 at 320 nm to 1600 J/cm2 at 550 nm. J or I'm working with a ultra-short laser to measure the non-linear refractive index of several materials, through broadening spectral due to self-phase modulation in waveguides.
