LD-PD can Customize AR coating (anti reflective coated R<0.2%) or HR coating(high reflective thin film optical coated for different wavelength bands. And we now can do Bare optical fiber polishing, super cleanses surface, flat or angle polish tip Single mode optical fiber，and Polarization Maintaining optical fiber cables (PM fiber Panda) AR coated. This coating pigtails widely used in Fiber laser pump source diode laser optical fiber tail coupling, High power laser mirror, lens AR or Dichroic coated.Also we can do dual operation wavelength with High Reflectivity.
