摘要:
The present invention: directs a light beam (a) onto a prism (21) having a metal thin film (25) formed on a specific surface (23), changing the angle of incidence (?) relative to the metal thin film (25) in a state of full reflection; measures light emitted on the surface (25a)-side of the metal thin film (25) as a result of the reflection of the light beam (a) by the metal thin film (25); determines the angle of incidence (? 5) at which to direct the light beam (a) onto the metal thin film (25) on the basis of the measured variation in light intensity; adjusts the direction in which said light beam is directed so that the light beam (a) is directed onto the metal thin film (25) at the determined angle of incidence (? 5); and measures fluorescent light emitted at the surface (25a)-side of the metal thin film (25) while the light beam (a) is being directed in the adjusted direction.

Disclosed is a method for manufacturing a near infrared reflective body in which a near infrared reflective film is manufactured that has excellent manufacturing cost performance, is capable of being employed over a large area, has excellent application stability, and has excellent resistance to refractive index irregularity in the surface. A method for manufacturing a near infrared reflective film in which a high refractive index layer and a low refractive Index layer are alternately laminated on a support body, wherein the difference in the refractive index of adjacent high refractive index layers and low refractive index layers is at least 0.3, and the near infrared reflective film is formed using a high refractive index layer application fluid and a low refractive index layer application fluid such that, if the viscosity of the high refractive index layers and low refractive index layers at 15 °C is ·15 and the viscosity at 45 °C is ·45, the viscosity ratio (·15/·45) in each case is at least 2.0.
摘要:
An object is to provide an illumination device in which uneven light emission that a user may perceive is suppressed. To achieve the object, an illumination device is adopted that includes a power feeding portion and a surface light emitter including a light-emitting surface configured to emit light in accordance with a voltage applied by the power feeding portion and to cause light emission in the shape of a surface. The surface light emitter generates a spatially periodic luminance variation having a substantially constant amplitude.
