Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a one-light transmitting sheet that transmits visible light and reflects infrared rays. More specifically, the present invention relates to a light-transmitting sheet that transmits visible light and reflects near-infrared light to infrared light.

In general, conductive metal thin films such as gold, silver, copper, and various alloys containing these as main components are sandwiched between transparent high refractive index dielectric layers, and the thickness of each 41% acid-N film is measured by controlling the thickness of the laminate. It is known that by doing so, it is possible to obtain a device that selectively reflects light in a constant wavelength range.

In particular, the laminate, which is transparent in the visible part and selectively reflects phosphoric acid waves in the infrared rays, is useful as a heat ray reflective film.

It is effective from the point of view of energy saving in houses, use of solar energy, etc. However, energy saving in buildings, houses, etc.
In order to improve the efficiency of four-pressure utilization in the field of solar energy 6j, the button is used to increase the visible light part (4!'i 0 ny (~700 nm) in the energy distribution of solar sand.
* Transmission characteristics of near infrared f4B (701μm~ztoonm> It is more effective for heat insulation to further reduce the transmission characteristics of the near-infrared rays, where there is 11. Further improvement of heating and cooling effects by improving the ability to block solar energy that enters through the windows of buildings, containers, and vehicles;
It can be applied to increase the pressure in the history of cold storage effect in frozen and refrigerated showcases.

These optical interference filters with selective transmission are generally Fabry-Pérot filters (Fabry-Pérot filters).

l, sandwich a transparent dielectric material with a VC specific optical thickness between opposing semi-transparent mirrors 4-! It is known as the interference phoenix 11 and I9 that transmits light of constant wavelength.

By applying this Fabry-Bello filter, it is possible to create a custom-made selective light transmittance sheet with high near-infrared transmission characteristics and near-infrared reflection. 3.6
It is shown in No. 82528 Meihomon type. That's f, f+

Ag/A+20s is a 5 tl adult with a transmittance of 70% or more from 4001 m to 700 nm and a reflectance of about 10%, a transmittance of 10% or less from 700 nm to 2500 nm, and a reflectance. A selective light transmitting laminate having a light transmittance of about 90% or more has been obtained.

In the Fabry bellows filter, by thinning the gold film, which is a semi-iN transient reflector, the transmission wavelength width can be expanded and the transmittance can be improved by 1. It is known that the transmission wavelength width will be narrowed by lowering 21. If you surround the rate and thickness of one body with nlη and more attraction! i 0011nl If the metal film is selected so as to obtain the K transmission peak and the metal film thickness is made sufficiently thin, it is possible to create a car that constitutes a 7・r Luther with good transmission characteristics in the FM section and good near-infrared σ) cutoff characteristics σ). . Conventional filters θ) have been mainly used for M'lV'/IY circular studies, and from that point of view, they have stable optical constants, absorption σ) less oxidation, oxidation, etc. 'The snout was used as a unit for the transparent T.

This Jt means that the technology for uniformly covering the surface of a gold kT4 thin film layer over a thickness of 1yi with a metal oxide film is still an incomplete technology.

Gold 1ii! If the metal oxide film J is thin (less than 50λ crucible), it is possible to form a metal oxide film from gold JQPA by isobaric thermal oxidation, but as in the present invention, V
It can be said that it is impossible to uniformly form the C+, oooAa film J9 over a large area on a technical scale.

We have been diligently studying the application of Kakoro Fn adult to energy saving applications such as solar energy utilization.

As a result, by uniformly coating an organic compound with a refractive index of 1.35 to 1.65, we can create a chemically clear and uniform optical dielectric. It has been found that it is possible to form the body layer (C1).

Conventionally, organic compounds are characterized by their optical non-uniformity,
Due to the large optical loss, etc., it has not been used in optical detergents, with some exceptions. However, the transparent electrically shielding layer (G) made of a compound having a loaf rate of 1.35 to 1.650 is optically homogeneous over a large area and uniformly coats the metal thin film layer as a layer without optical fluctuation. The present invention was achieved by discovering that it can be coated as a.
