An optical sensor system () has an optical detector () with an active detector area () and a detector output signal (). A test-signal optical source () has a controllable optical source () having an output of a wavelength detectable by the optical detector (), and a test-signal director () that directs the output of the optical source () to the active detector area () of the optical detector (). A housing () encloses the optical detector () and the test-signal optical source (). A test instrumentation controller () controls the operation of the optical source (), and receives the detector output signal () for evaluation.
