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.

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.

There is no such thing as a stupid question but there are a lot of inquisitive idiots.
