Just about everyone has seen a television show or movie in which a criminal suspect is questioned while detectives watch from behind a one-way mirror. How does a piece of glass manage to reflect light from one side while remaining clear on the other?

The secret is that it doesn’t. A one-way mirror has a reflective coating applied in a very thin, sparse layer. So thin that it’s called a half-silvered surface. The name half-silvered comes from the reflective molecules that coat the glass so sparsely that only about half the molecules needed to make the glass an opaque mirror are applied.

What is One-Way Mirror?

At the molecular level, there are reflective molecules speckled all over the glass in an even film but only half of the glass is covered. The half-silvered surface will reflect about half the light that strikes its surface, while letting the other half go straight through. It turns out that half-silvered mirrors are also essential to many types of lasers.

How One Way Mirror Works

So why doesn’t the “criminal suspect” see the detectives in the next room? The answer lies in the lighting of the two rooms. The room in which the glass looks like a mirror the light is kept very brightly lit, so that there is plenty of light to reflect back from the mirror’s surface. The other room, in which the glass looks like a window, is kept dark, so there is very little light to transmit through the glass.

Where ever the light is greater is the one way mirror effect.

Much like driving downtown in the day time and seeing the mirror pane glass on the high rise buildings, you only see reflections in the daytime.

Then drive downtown at night, when the lights are on in the building you can see through the mirror pane into the offices because the light is more great inside the buildings.

“Mirror Pane” is the official name for a One Way Mirror

It was called VeraTran years ago but that was the company name of who made it and now there are lots of companies that make it. The mirror side of it is a “first surface” in the process of making a mirror. The next surface will be that backing put on that you are more familiar with. That backing is a gray coat of paint to protect the silvering on the 1st surface.

Give us a call, we carry and install the mirror pane for privacy room, for security rooms, and sometimes for a TV cover in the bathroom.
