Request InfoReynard CorporationReynard Corp. has announced the Bullseye inverted apodizing neutral density filter, eliminating undesirable intensity variations in optical systems. Filter density increases radially from a clear center, where light is usually at its peak intensity, to the outside edge, where it becomes completely opaque. The Bullseye filter can be designed for most distribution functions, such as Gaussian, regardless of the beam’s size. The distribution function, substrate type and bandwidth are a function of the customer’s specific requirements. Density gradients can be customized to...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/2/2024Optical Processors and FilterThe WaveShaper® 1000A, 4000A, and 500B from Coherent are programmable optical processors and a filter, respectively, capable of testing optical components and networking systems in the U- and...Photonics.com 10/24/2023Computer Generated HologramThe 9-inch computer-generated hologram (CGH) from Arizona Optical Metrology enables snapshot metrology of up to 7-inch diameter convex optics.
