Problems solved by technology

The metal layer of the one-way glass with this structure is easy to detach from the glass surface, and more importantly, as time goes by, the metal in the metal layer is oxidized, resulting in a reduction in the perspective of the one-way glass or causing the one-way Glass cannot realize the function of one-way perspective
[0005]Moreover, the above-mentioned existing one-way perspective glass uses the difference between strong and weak light sources on both sides to spy on the supervision method, and there are limitations such as too obvious artificial traces and no concealment

Abstract

The invention discloses a one-way perspective glass which comprises a glass substrate, a composite dielectric medium layer, a metallic reflection layer, a metal oxidation prevention layer, a light absorption layer, and a composite medium protection layer which are arranged on one surface of the glass substrate in sequence in a superposed manner. The one-way perspective glass has a firm, compact and simple structure, can improve the reflectivity of light on the side of an observation object, and can reduce the reflectivity of light on the side of an observer, which ensures that the observation interference is less. The preparation method of the one-way perspective glass has simple preparation procedures, production efficiency is improved, production cost is lowered, and the method is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of electric light sources, and in particular relates to a one-way see-through glass and a preparation method thereof. Background technique [0002] Because of its one-way perspective function, one-way glass needs to be used in some specific places, especially in places such as prisons, interrogation rooms of public security agencies, university research institutions, and large conference rooms. Glass. [0003] In the prior art, the one-way glass generally adopts the structure of sticking a film on the ordinary glass. The one-way glass with this film structure has the disadvantages of poor one-way perspective effect, and is easy to be damaged and peeled off. [0004] And another kind of one-way see-through glass in the prior art is to adopt metallized layer on the glass surface. The metal layer of the one-way glass of this structure is easy to detach from the glass surface, and more importantly, as time goe...
