    I Calculate Retinal irradiance - from photometric units

    Hi. Thank you for your answers. Yes, the main goal is to apply to alive people and I'm aware of the exposure standars for the different wavelengths. For example: https://www.researchgate.net/publication/326358672_Blue_Light_Hazard_Are_exposure_limit_values_protective_enough_for_newborn_infants...

    I Calculate Retinal irradiance - from photometric units

    Thank you for your answer. The manufacturer datasheet does not provide the actual watt ouput of the LED..only the intensity in lumens In the manufacturer website there are some informations about the LED characteristics: The Watt values they refer, are related to the consumed power, not the...

    I Calculate Retinal irradiance - from photometric units

    Thank you for answer. I'm planning to apply blue stimulus to the human eyes. What do you mean with 'Edit as in radiometer?' ? Thanks!

    I Calculate Retinal irradiance - from photometric units

    Thank you for your answer. I am planning to apply the stimulus to human dark adapted eyes. So, I should not use the scotopic curve instead of the photopic? http://hyperphysics.phy-astr.gsu.edu/hbase/vision/bright.html#c4 In the scotopic curve, the efficacy conversion factor is 1700 lm/W. At...

    I Calculate Retinal irradiance - from photometric units

    I have been trying to calculate what retinal irradiance value I get with a 1 blue LED system. Since the manufacturer didn´t give the spectral distribution information, I will approximate LED as a monochromatic one (using the 460 nm peak). From the datasheet, the LED intensity range goes from 6...
