![]() ![]() ![]() UV light intensity unit conversation (UV light intensity measurement units):ġ Joule (J) = 1 Newton * Meter = 1 Watt (W) * Second (S)ġW/m 2 = 1000mW / 10000 cm 2 = 0. Intensity is the quantity of energy the wave conveys per unit time across a surface of unit area. Don't believe that, it must be a lie! The UV light intensity units conversation are listed below: The light energy flux may be expressed in terms of the incident x-ray energy flux and the x-ray absorption and conversion properties of the scintillator (7,8,9). So when you see that some UV energy meters have slow sampling speeds, the seller tells you how accurate their uv energy meter is. Luminous intensity is defined as dId / d, where d is the luminous flux (light energy flux in watts per m2) emitted within a solid angle d. When the sampling speed reaches 2000 or above, the change in the power value is small and can be neglected. The faster the sampling speed, the more accurate the energy accumulation value. The second link says that in order to calculate the light intensity of the second bulb, one must divide its distance squared by that of the distance squared of the standard bulb's intensity (other bulb) and then multiply it by the standard bulb's intensity, which was assigned a comparative number of one. Calculating the energy value requires accumulating the power value. So why is the sampling speed so fast? That is because the power value is varied. So what does this UV energy unit mean in the uv energy meter? Simply speaking, the power value is constantly changing during the measurement process and xxxx times/second is the sampling speed of the uv energy meter per second. Usually we will see such a UV energy unit in the UV energy parameter table, sampling speed: "xxxx times / sec". Light energy at the test material surface is a measure of cumulative intensity exposure (UV light intensity x time), quantified as millijoules/cm2 and is simply: And it is measured in the units of millijoules per square centimeter (mJ/cm2), which is energy received per unit area in a given measurement time. The UV radiation intensity is measured in the units of milliwatts per square centimeter (mW/cm2) which is energy per square centimeter received per second. ![]()
