BARRINGTON, N.J., May 20, 2015 — Beam Twisters from Edmund Optics Inc. are suitable for pairing with slow-axis collimators for complete laser beam collimation.
The new beam-shaping lenses are used to rotate beams emitted by individual laser bars by 90° using a preassembled, proprietary molded-glass twister array combined with a fast-axis collimator lens of S-TiH53.
Light emitted initially from a laser bar appears to be in the shape of a line. Once it has passed through the Beam Twister, the laser bar's light transmission is transformed into a square shape by its 90° rotation. This square configuration is beneficial to a laser line because it allows the beam to be focused into a spot, which may be used with fiber optics or a variety of other beam-delivery systems.
Providing >97 percent transmission, the lenses feature near-IR coatings with an average reflectance <0.5 percent at 800 to 1000 nm. A 24-emitter model with 400-μm pitch and a 19-emitter version with 500-μm pitch are available.
