Bullseye® 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. Linear Apodizing filters also available! Prototypes to volume production, ISO9001:2015 certified, ITAR registered & Cybersecurity compliant.
