Irradiance to fluence
WebJun 20, 2024 · In radiometry, radiant exposure or radiant fluence is the radiant energy received by a surface per unit area, or equivalently the irradiance of a surface integrated … WebRadiant energy received by a surface per unit area, or equivalently irradiance of a surface integrated over time of irradiation. This is sometimes also called "radiant fluence". Spectral exposure: H e,ν: joule per square metre per hertz J⋅m −2 ⋅Hz −1: M⋅T −1: Radiant exposure of a surface per unit frequency or wavelength.

WebMay 20, 2024 · FIG. 3 – Spherical irradiance (fluence rate) For UVGI applications, we are interested in the ultraviolet dose, or fluence, of the droplet, measured in millijoules per square centimeter. Unfortunately, there are no practical instruments to accurately measure ultraviolet fluence, apart from spherical actinometers – hollow quartz spheres ... WebFlux and Irradiance 1 In examining terminology for illumination, it is useful to separate the spatial considerations from the spectral concerns. In many cases, the spatial and …
WebThen, by using the calculated intensity-wavelength dependence for each lamp, we estimated the penetration depth of each UV wavelength into the skin when using that specific irradiance, and as the inset shows, the cutoff fluence considered was 10 −6 (Fig. 2B). The analysis shows that, as expected, UVB radiation stays in the epidermis and in ...
