Irradiance to fluence
WebIf the irradiance is constant in time, the fluence (UV dose) is given by E × t, where t is the exposure time in seconds. In North America, it is common to use the units mW cm–2 for … In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m ). The CGS unit erg per square centimetre per second (erg⋅cm ⋅s ) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry where such usage leads to confusion with radiant intensity. In astrophysics, irradiance is called radiant flux.

WebFluence response Both fluence rates and irradiance of light are important signals for plants and are detected by phytochrome. Exploiting different modes of photoreversibility in this molecule allow plants to respond to different levels of light. WebThe Irradiance (continued) The irradiance (or intensity) is the magnitude of the time average of the Poynting vector: Since the time-dependence of S is given by a cos2, we must take the time average of this function. 22 (,) cos( ) 00 Srt c E B k r t The average of cos2(x) is ½:
WebDose (Fluence), Irradiance and Contact Time - Theory behind the UV-Tube. To inactivate a given microorganism the water must be hit with a certain amount or dose of UV light. Dose, more properly referred to as fluence, is determined by variables associated with the design and operation of the UV disinfection device, as well as the ... WebRadiometry Irradiance E [W/cm 2] At a point of a surface, the radiant energy flux (or power) incident on an element of the surface, divided by the area of the surface. The power P [W] that irradiates a surface area A [cm2] is called the Irradiance E …
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 ... WebFluence-response curves for the induction of seed germination after 24 hours pretreatment at 35 degrees C of Rumex obtusifolius and Arabidopsis thaliana show two phases of response: (a) a very low fluence-response (10(-4) - 10(-1) micromoles per square meter) and (b) a low fluence-response (1 - 10(3) micromoles per square meter).
WebThe light was delivered at an in-air fluence rate (irradiance) of 74 mW/cm 2 for 34 min, totaling an in-air fluence (i.e., light dose) of 150 J/cm 2. After irradiation, the animals were sutured and received 2.2 mg/kg of analgesic intramuscularly (Banamine ®, Coopers Brazil Ltda, Cotia, SP, Brazil). Thirty hours after the end of the PDT ...
