We have the circuit show in this article [login to view URL] The photodiode is the Digikey model 1125-106ND The JFET OPAMP is the AD820ANZ. Capacitance and resistance are shown in the diagrams. Problem The system is too sensitive, in full light, the output signal is saturated. Question What to add in the editing to decrease its sensitivity?

1st. sol. First the circuit is build to do that just try different type of photodiodes which are operating outside visible range, 2. solution. just different circuitry to, rather going for infinity gain go for manual gain which can be change according to situation. just PM me for full and final solution in short time
