I am building a fiber optic blood oximeter which is founded on the basis of the different light absorption of oxyhemoglobin and deoxyhemoglobin. My red LED can withstand much more current than the IR LED. Should I drive them with the same current or can I use different current values (will this affect my output on the photodiode reception end?)?
