Request InfoReynard CorporationBullseye® apodizing filters radially modify beam distribution in optical systems. Standard Gaussian or customized filters inserted in line with a light source reduce undesirable intensity variations. Configurations include both dark-in-the-center, typically used to reduce low-frequency variations or to create top-hat wave fronts, and clear-in-the-center functions, typically used to reduce high-frequency variations outside of the main beam profile.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2024 IssueCo-Packaged Optics SwitchThe 51.2T co-packaged optics (CPO) network switch system from Micas Networks in collaboration with Broadcom Inc. was made for adoption in AI/machine learning cloud infrastructures.
