Low refractive index adhesive
Webwindow and lens products. Because of its low absorption and high damage threshold, it has become an ideal choice for excimer laser optics. The low refractive index of calcium fluoride also enables it to be used without antireflective coating. The Knoop hardness of calcium fluoride is 158.3. Calcium fluoride (CaF2) window sheets are made of vacuum UV-grade … WebA primary performance figure is the refractive index at the optical wavelengths of interest. Various fluids have been developed for matching certain common optical materials like fused silica, BK7 or certain crown glasses. Depending on how strongly reflections must be suppressed, there is a larger or smaller tolerance for the refractive index.
