Twister/Collimator rotates laser bar beams 90° to form square.

Press Release Summary:

Using preassembled, molded glass twister array combined with fast axis collimator, Beam Twisters™ rotate beams emitted by individual laser bars by 90°. Light emitted from laser bar, after passing through product, becomes square shaped. Providing >97% transmission, RoHS-compliant products feature NIR coatings with average reflectance of <0.5% at 800–1,000 nm. Both 24-emitter model with 400 µm pitch and 19-emitter version with 500 µm pitch are available.

Original Press Release:

Beam Twisters(TM) Provide 90° Rotation of Laser Bar Beams

Barrington, N.J. — 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 500 µm 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.
