Beam Transformation Systems support 600-1,600 nm wavelengths.

November 24, 2014

Available with pitches of 200, 400, and 500 µm, Beam Transformation Systems bundle and symmetrize asymmetrical laser beams generated by diode laser bars and mini bars. Residual divergence ranging from 12 to under 5.0 ensures high beam quality. To achieve best possible performance for specific application, systems use 4 Fast Axis Collimators that have been optimized for short focal lengths. Read More

Slow Axis Collimators work with laser bars.

August 20, 2014

Consisting of monolithic array of cylindrical lenses that are designed to collimate individual emitters of laser bar, Slow Axis Collimators provide numerical aperture of 0.05, surface accuracy of λ/4, and low curvature deviation. RoHS-compliant units feature standard AR coating for 790–990 nm and provide greater than 99% transmission. Measuring 12 mm long x 1.50 mm high, collimators come in 50, 100, and 150 µm sizes, all with 500 µm pitch. Read More
