The D2-120 from Vescent is a Fiber Optic Coupler that operates at wavelengths of 760 nm, 767 nm, 770 nm, 780 nm, 785 nm, 795 nm, 808 nm, 838 nm, 852 nm, 895 nm, 935 nm, 1064 nm, 1083 nm, and 1092 nm. It has a minimum fiber coupling efficiency of 50% and an isolation of 30 dB. This fiber optic coupler is designed to facilitate the coupling of a laser beam into either a single or multimode optical fiber. It incorporates an optical isolator and has an aspheric anti-reflective (AR) coated condensing lens. This fiber optic coupler has six degrees of freedom for alignment optimization: 3 linear (x, y, z), 2 angular (azimuth & elevation), and 1 rotational (for PM fibers). It supports FC/APC & FC/PC fiber connectors and is available in a package that measures 101 mm x 65.4 mm x 43.2 mm.
