Detection angle of LED used as sensor

Hello,

When a LED is used as a light sensor, is the detection angle the same as the diffusion angle of the component when used as a light emitter ?

Thank you in advance.

Yes.

In optical systems light can travel in opposite directions through a given optical path with equal facility - otherwise you could build a perpetual motion machine that pumps heat, violating the laws of thermodynamics.

Is DH rubbing off on you :smiley:
