How To Make Front Surface Mirrors
Clearly, front surface mirrors are superior to conventional back surfaced mirrors. A front surface mirror, as the name suggests, is a mirror in which the reflective surface exists unprotected, on the top surface of the glass.
Then again, some front surface mirrors are sometimes coated with various materials. A good example of this is the Anti-Reflective (AR) coatings that are sometimes added to some specialty mirrors.
In most cases, the reflective coating is pure silver and it is chemically deposited on the glass or produced by vacuum depositing special compounds in a vacuum chamber. In some cases, other metals are used as well.
In the case of an ordinary back surface mirror, the reflective coating (did you know that pure silver is used to make even the cheapest of mirrors?) exists on the reverse side of the glass.
The problem with using back surface mirrors for making things like stereo beam splitters, image viewers that use a mirror or for making kaleidoscopes is potential image degradation. In some cases, the glass used to make cheap mirrors has a greenish tint and this can sometimes affect the image.
Because a front surface mirror reflects far more light than a back surface mirror, front surface mirrors are ideal for creating light reflectors.
Front surface mirrors have many interesting and useful applications. For example:
Making, restoring, and repairing kaleidoscopes
Improving or constructing inexpensive optical toys and devices
Making specialty mirrors for laser and optical experimenters
Improving stereo viewers
Building beam splitters
General photographic applications like reflecting light and images.
Our latest guide will explain, in simple terms, how to make your own high-quality front surface mirrors. You will not need costly, hazardous, and hard to find tools or chemicals. Our simple techniques do not require that you learn to silver glass.
Will the mirrors you make be equal to high-end lab quality mirrors? Well, no, most likely not. Many front surface mirrors can be costly and quite frankly, for most users, you do not need expensive mirrors.
When you learn how to make your own mirrors, you do not need to worry about damage, simply make another mirror; the process takes surprisingly little time. Also, when you learn how to make your own mirrors, you do not need to search the Internet for a supplier.
We recently updated our lab guide to teach you how to restore reflex mirrors for SLR cameras as well as a chapter that will teach you how to properly clean all kinds of glass surfaces. There are several time-tested methods of cleaning glass as well as front surface mirrors. And yes, you can clean a front surface mirror if you know what you are doing.
