0.532 micrometers to 1.064 micrometer frequency-multiplied antireflection coating for use on surface of large-curvature lens

The invention provides a 0.532 micrometer to 1.064 micrometer frequency-multiplied antireflection coating for use on the surface of a large-curvature lens. The coating comprises a transparent substrate and an antireflection film system. The antireflection film system comprises alternately stacked 12 film layers of high refractive index dielectric film layers and low refractive index dielectric film layers and is applied to the surface of the large-curvature lens having a curvature radius to aperture ratio less than 1; glass substrate adaptability is high; tolerance to the refractive index n of the high refractive index coating material caused by difference in parameters of different coating machines is high, and stability is high; namely, the refractive index of the transparent substrate is applicably 1.46 to 1.60, the refractive index n of the high refractive index material Ta2O5 is 1.946 to 2.126, and optical performances, namely residual reflectivities, of points of the surface of the large-curvature part, at the 0.532 micrometer to 1.064 micrometers wavelength positions, are all greater than 0.4%.
