More Information
Summary:An optical product comprising a base member and an optical multilayer film formed directly on or indirectly above a film formation surface of the base member. The optical multilayer film reflects light on a short wavelength side and suppresses reflection of light on a longer wavelength side than the light on the short wavelength side, and has a first layer to an eighth layer counted from the base member side, the first layer is a first Al layer, the second layer is a first low-refractive-index layer, the third layer is a first high-refractive-index layer, the fourth layer is a second low-refractive-index layer, the fifth layer is a second Al layer, the sixth layer is a third low-refractive-index layer, the seventh layer is a second high-refractive-index layer, and the eighth layer is a fourth low-refractive-index layer.
