Beam Twisters

Share this on social media:

Edmund Optics (EO), the premier provider of optical components, introduces new Beam Twisters.  These beam shaping lenses are used to rotate the beams emitted by the individual laser bars by 90° using a preassembled proprietary molded glass twister array combined with a fast axis collimator.

Assembly includes fast axis collimator and rotation array

Beam Twisters are comprised of an assembly of a fast axis collimator lens of S-TiH53 and a beam rotation lens array. Light emitted initially from a laser bar appears to be in the shape of a line. Once it has passed through a Beam Twister, the laser bar's light transmission is transformed into a square-shaped appearance 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.

Greater than 97% transmission

 Providing greater than 97% transmission, RoHS compliant Beam Twisters feature NIR coatings with an average reflectance of less than 0.5% at 800-1000nm. A 24 emitter model with 400μm pitch and a 19 emitter version with 500μm pitch are both available. Beam Twisters are ideal for pairing with a slow axis collimator for complete laser beam collimation. Beam Twisters are in-stock and available for immediate delivery for fast turnaround and excellent value.
