Gradient Mirror Coatings


GRM / Radial Gradient Mirror
GA (Gaussien), SG (Super Gaussian), BE (Bessel), PR (Parabel)

 The Radial Gradient Reflection Mirror Coating is a mirror with a varying reflectance as a function of the radius. This mirror enables an optimal adaption of the beam profile to the application. A small and precise focus as well as a specified intensity profile are easily achievable. The wide range of the shapes of reflectance provide an additional degree of freedom in optical system design. Typical beam shapes are Gaussian (GA), Super Gaussian (SG), Bessel (BE) and Parabel (PR) but also customized designs are available.
The Gradient Mirror Coatings are fabricated with NANEO's proprietary precision coating technology on IBS (Ion Beam Sputtering) coating machines. NANEO achieves unique layer thickness precision. IBS provides the most dense, low loss, stable and endurable optical coatings among the optical coating technologies. (more details)
