The 77596 Laser to Fiber Coupler uses an achromatic GRIN lens to focus a 400 to 900 nm TEM00 laser beam into a 50 µm core single fiber. One end has a 1-32 external thread to screw to a laser head; the other has an SMA connector to couple to the fiber. The focus of the lens is at its end; the fiber is screwed in until it butts against the lens. The coupler has a tilt plate mechanism. Tilting the lens and fiber plate with respect to the beam causes the focused spot to move across the fiber end for precise positioning at the fiber core.
