C-Lens
Micro lens (C-lens), used to couple collimated beam and divergent beam at fiber pigtail, is the fundamental elements used in optical communication devices. Pigtail and c-lens can been assemble into collimator to realize various functions of optical signal processing in collimated beam, and further fabricated into isolat or, circulator, op tical switch, attenuator and dense wavelength division multiplexer (DWDM) etc.
C-lens have several advantages including low insertion loss, wide working distance range and low cost. PHOSCTECH can provide various C-lens as customer's demanded.
