OPTICAL BODY AND WINDOW MATERIAL PROVIDED WITH THE OPTICAL BODY |
摘要 |
An optical element includes an optical layer having an incident surface on which light is incident and a wavelength-selective reflective film formed in the optical layer. The optical element selectively directionally reflects light in a specific wavelength range while transmitting light in a wavelength body other than the specific wavelength body. Of light incident on the incident surface at an incident angle (¸, Æ) (where ¸: the angle between a normal to the incident surface and incident light incident on the incident surface or reflected light exiting from the incident surface; and Æ: the angle between a specific line in the incident surface and a component of the incident light or the reflected light projected on the incident surface), the optical element selectively directionally reflects the light in the specific wavelength range in a direction other than specular reflection (-¸, Æ + 180°) while transmitting the light in the wavelength range other than the specific wavelength range, and has transparency to the light in the wavelength range other than the specific wavelength range. |
