Request InfoEdmund Optics Inc.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...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/15/2023Spatial Light ModulatorsSpatial Light Modulators from Electro Optical Components Inc. use translucent and reflective liquid crystal micro-display technology to modify the amplitude and phase of incident light one pixel at a...Vision Spectra Spring 2024 IssueWide-Angle Thermal LensThe 80° wide angle thermal lens offering from Teledyne FLIR is designed to enable the visualization of assets in a large target area, supporting continuous condition monitoring and early...Photonics.com 4/5/2024Ruggedized LensesThe 1.4-in., 45-MP MPT-R Series and 1-in., 20-MP MPZ-R Series (shown) from Computar® are 45-MP and 20-MP ruggedized lenses for harsh environments.
