Abstract
An optical measurement apparatus operable with a test specimen has a light source with a laser having an output beam, and a beam splitter that splits the output beam of the laser into a first split beam and a second split beam. A test specimen holder holds the test specimen therein. A first optical fiber receives the first split beam and directs the first split beam against the test specimen in the test specimen holder. The apparatus further includes an instrumentation module. A second optical fiber receives the second split beam and conducts the second split beam to the instrumentation module. A third optical fiber receives signal light from the test specimen in the test specimen holder and conducts the signal light to the instrumentation module.
