Conversion between light intensity meter and optical power density

Use this Optical Density (OD) Calculator to convert between intensities (I0 and I), transmittance (T), percent transmittance (%T), and optical density/absorbance (OD or A). You can also optionally use Beer-Lambert law to solve for concentration, path length, or molar. The home page of optics toolbox. Convert laser average power and energy per pulse to average power density/irradiance and average power with this online calculator. Works for both Gaussian and flat beam profiles. It is commonly reported in W/m², W/cm², or mW/cm². Note: This calculator assumes uniform power distribution over the chosen area. Select an area method matching. Radiant (luminous*) energy is the energy of electromagnetic radiation.
