Radiant Exposure Calculator
Posted by Dinesh onIn 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 over time of irradiation, and spectral exposure or spectral fluence is the radiant exposure per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
Formula:
He = Ee × t
where,Ee = The irradiance (power of electromagnetic radiation per unit area incident on a surface)
t = Time of exposure ( the length of time a camera's shutter is open when taking a photograph)
He = The radiant exposure
