Heat-blocking glass |
摘要 |
A heat-blocking glass comprising: a first layer of infrared rays-blocking film of any thickness formed on a substrate; a plurality of intermediate layers from a second to a (2n+2)th layer (n: positive integral) stacked on said first layer, the optical thickness of each intermediate layer being lambda /4 ( lambda : design wavelength); and an uppermost (+3)th layer of a lambda /8 optical thickness. The refractive index of the first layer is smaller than the refractive index of the second layer. The refractive index of each layer from the second layer to the uppermost layer is arranged so that high-refractive-index layers and low-refractive-index layers are alternately stacked, the second layer being disposed as a high-refractive-index layer.
