For our optical measurements, the light is sent to the sample through the excitation arm, whereas the reflected or emitted signal is collected in the detection arm. All of the lenses are aspheric. BS, beamsplitter; CCD, charge-coupled device used for imaging the sample; LP, linear polarizer; λ/2: half-wave plate; λ/4, quarter-wave plate.
