The D2-120 is designed to facilitate coupling of a laser beam into either a single or multimode optical fiber. This module incorporates a 35 dB optical isolator, prior to the fiber facet, to reduce optical feedback. An FC fiber receptacle is provided with an aspheric AR-coated condensing lens and six degrees of freedom for alignment optimization: 3 linear (x, y, z), 2 angular (azimuth, elevation), and 1 rotational (for PM fibers). The incoming beam height matches other D2 series lasers and optical modules.
