    Both beam-shaping optics and single-mode fiber-coupling optics are available. The company sells lenses that transform the divergent diode-laser beams into collimated beams, lenses that shape the beam into circular, linear, or rectangular spots, and single-mode fiber couplers for fibers with 3- to 10-µm cores. Lenses have focal lengths from 4.5 to 90 mm for wavelengths from 400 to 1500 nm.
