Feature
Toroidal mirror, B4C coating
Grazing-incidence toroidal mirrors are used in experimental systems that require broadband high-order harmonic focusing, such as attosecond science. NTT-AT's toroidal mirrors are used by researchers at many universities and research institutes due to their shapes and various coatings that can be tailored to suit their needs.
Direct-incidence toroidal mirrors can be used in experimental systems where aberrations with spherical mirrors are an issue. Depending on your usage conditions, you can choose between high reflectance, broadband, or narrowband EUV multilayer coatings.
