Request InfoB&W Tek LLCThe BWN series solid-state lasers from B&W Tek Inc. are self-contained, double TE-cooled red and green devices. They operate in a temperature range from 10 to 35 °C with quiet and stable output, the company says. Their high mode quality and low divergence make them suitable for beam focusing and long-distance beam positioning applications. The compact power supply can be in- tegrated into a custom system and has all applicable safety features, including a key-lock switch, an emission indicator and a remote interlock connector. Output power ranges from 4 to 20 mW at 532 and 635 nm.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/31/2022Broadband and Wide-angle Laser Line MirrorsBroadband and Wide-angle Laser Line Mirrors from Knight Optical Ltd. feature an Ion Beam Sputtered (IBS) coating to meet the demanding requirements sought by laser system manufacturers. ...Photonics Spectra July 2022 IssueSolid-State LasersTruDisk high-power, solid-state lasers from TRUMPF SE and Co.
