For example, infrared absorption spectrometers are not equipped even when measuring heterogeneous samples such as coal powder.
Nor was it added to infrared lamps used as heat sources. In addition, integrating spheres used in infrared spectrum measurement equipment for special analysis purposes have a rough gold-plated inner surface, and building window glass has a rough or uneven surface. Infrared scattering measures such as providing a reflector were taken.

663 (1982)), but in this method, the true background was unclear and the determination of straight lines and curves as the background had to rely on human intuition, which caused problems in analytical accuracy. Furthermore, since the infrared light emitted from the infrared lamp was non-uniform, it was locally heated, causing problems depending on the application. Window glass also has insufficient scattering and tends to be locally heated, and electric stoves have similar problems.

イルド温度分布になっ居住性がよくなる。The infrared scattering agent of the present invention has high infrared transmittance and high scattering rate. By using this infrared scattering agent as a window agent when measuring an infrared absorption spectrum, the background of a heterogeneous sample can be removed, thereby increasing the accuracy of analysis. Furthermore, by coating the inner surface of an integrating sphere in the infrared region, light scattering properties can be ensured without roughening the surface, and therefore there is no need to control surface roughness. When used in infrared lamps, infrared heaters, etc., it can provide uniform heating, and when used as a heating device, it can provide mild and uniform heating. Also, if you use it for cooking, you will be able to heat it evenly. When laminated on the window glass of a building, it prevents local heating inside the room due to sunlight and creates a mild temperature distribution throughout the room, improving livability.
