Product Describe

One-way perspective glass (also known as unidirectional glass, atomic mirror, single mirror, double-sided mirror) is a kind of glass with high reflection ratio to visible light. When the product is used, the reflecting surface (mirror) must be the light facing surface or the side facing the outdoor. When the outdoor is brighter than the indoor, the unidirectional perspective glass is similar to the ordinary mirror. The indoor scenery can not be seen outside, but the outdoor scenery can be clearly seen indoors. When the outdoor is darker than the indoor, the indoor scenery can be seen outdoors, and the outdoor scenery can also be seen indoors. The clarity depends on the intensity of outdoor illumination. Application: unidirectional perspective glass is mainly used for concealed observation windows and holes. The product can be used in karaoke, office, kindergarten, school, prison and other special places.

$Brief Introduction and Technological Principle of One-way Perspective Glass One-way perspective glass, also known as one-way glass, one-sided mirror, mirror glass, one-way visual, SLR glass, semi-reflective glass, magic mirror glass and so on. English name: one way glass、two way glass、half way glass, etc. It is a kind of special glass with high reflectivity and certain transmittance to visible light. The normal glass reflectivity of the observed surface is better, which is convenient for the human eye to capture the high light object image and not to capture the low light object behind the glass. The environment of the observation surface should be dim so that the person on the observation surface can see the high and bright object behind the glass and ignore the reflected object image of the observation surface. One-way perspective glass has special requirements for installation and use environment. The light intensity on both sides of the glass is obviously different, so the function of unidirectional perspective glass can be fully realized. A manufacturer suggests that the light intensity difference on both sides of the glass should be maintained at 8~10:1 and that the light intensity should be uniform. Large area unidirectional fluoroscopic glass production is based on the principle of optical refraction, using vacuum magnetron sputtering technology to arrange and combine the glass surface according to the membrane structure of high refractive index / low refractive index / high refractive index / low refractive index / high refractive index. Metal and metal compounds or dielectric film are coated on glass surface to form high and low reflectivity.$

Comparison of unidirectional perspective glass and common glass mirrors

Glass Type	High Grade Silver Mirror	Aluminum Mirror	Pure Chromium	One-way Perspective
Mirror reflectance%	90	70	60	50~90
Transmittance%	0	0	0	5~50

Figure I

From the table, we can see that the reflectivity of different kinds of unidirectional perspective glass is between 50%~90%, and the reflection range is relatively wide, which mainly depends on the environment of different application sites and is designed according to the needs of customers. Mirror reflectivity below 50 can not reflect the particularity of unidirectional perspective glass. The so-called semi-transparent concept, its specular reflectivity tends to 50, transmittance tends to 50.

Silver is an ideal high reflection material. The visible reflectance requirement of copper-free silver mirror below 6 mm is ≥85% in 6.7 of the national standard GB/T 28804-2012 of silver mirror. The ideal unidirectional perspective glass mirror reflectivity should be as high as 90%, but should retain a certain transmittance, usually not less than 5% is appropriate. The relationship between transmittance and reflectivity satisfies the following relationships:

Mirror reflectance transmittance (film and glass) absorptivity =100%

One-way perspective glass identification method

Are you worried about your privacy being peeped or leaked when you stay in a rented house or hotel? How to identify whether the high reflective glass in the room is a silver mirror or a one-way perspective glass with perspective function? You can refer to the following methods:

Fingertip touch discrimination method: Touch the fingertip to the surface of the mirror material to observe the fingertip image. Ordinary silver mirrors are silver-plated on the back, so there is a gap between the fingertips when touching the mirror surface. If the fingertips touch the fingertips, the glass is one-way see-through glass.
Scratch method

The traditional one-way glass production process is offline soft coating, and the film surface is relatively easy to scratch, so scratching the glass with a hard object is a good test method. If the surface can be scratched by hard objects, it can be determined as one-way glass.

Illumination method

Illuminate the glass surface with extremely strong light. If you use a mobile phone, the light must be completely attached to the glass surface. Keep your eyes close to the glass and observe the light. If the light shines through the glass, the glass is a one-way perspective glass.

It should be noted that, due to the use of glass laminated composite technology for the explosion-proof one-way perspective glass, the highly reflective surface of the single-piece one-way perspective glass may appear on the laminated layer. This situation is relatively difficult to judge.

Application place of one-way glass

One-way see-through glass is mainly suitable for places with concealment. The main applications are: public security interrogation rooms, detention centers, prisons, courts, recording rooms, observation rooms, karaoke, offices, school observation classrooms, mental hospitals, nuclear power plants, military security departments and other places.

Cleaning and maintenance of one-way perspective glass

One-way perspective glass is suitable for professional cleaning.

In routine cleaning, never use acid-base corrosive cleaning agents. Use clean water-resistant soft cloth and clean soft glass scraping treatment. The glass surface does not need to be repeatedly rubbed back and forth.
