The CLA-SMA is a UV-NIR range, 9 mm focal length lens assembly converts divergent rays of light into parallel rays. It has an effective aperature of 4 mm with NA 0.22 single core fiber. The CLA-SMA attaches to an SMA 905 connector of a fiber optic patch cord and fiber assemblies. When used with a fiber cord attached to a light source, the CLA-SMA produces a parallel (collimated) beam of light. When the fiber cord is attached to a spectrometer, the CLA-SMA provides a narrow acceptance angle and narrow field-of-view. It has a spectral range from 190 to 2100 nm.
