>Intensive phototherapy is provided at an irradiance of 30 mW/cm2 per nm or more (430–490 nm).
How do I read this? Do i have to multiply it for the wavelength? Is it
30 * 460 mW/cm^2 (13.8 W/cm^2)?
Please I can't wrap my head around this
ouch, don't do this at home
mW * cm^-2 * nm^-1 is a unit of spectral irradiance, not much to calculate
The spectral irradiance at 0.5 m from our 6333 100 watt QTH lamp is 12.2 mW m-2nm-1at 480 nm. This is:
all at 0.48 µm and 0.5 m distance.
0.0122 W/m^2 nm^-1
1.22 W/m^2 um^-1
