Fiber collimator
The fiber collimator measures 2.4 mm in diameter and 11.5 mm in length. It provides fiber-to-fiber coupling with 0.2-dB loss, -65-dB backreflection and 0.01-dB polarization-dependent loss. Active alignment of the grin lens during manufacturing results in a diffraction-limited beam suitable for use from -22° to +80°C.
