Collimator + PD
The combination of a collimator and a photodiode (PD) is a key solution for non-contact detection of free-space light. The core principle is that the collimator first converts the divergent light in the fiber into a parallel beam, which the PD then receives and converts into the corresponding electrical signal, thereby enabling online monitoring of optical power without interrupting the fiber link.
