A first surface mirror (also known as a front surface mirror) reflects light directly from the coating that is applied to the polished or working surface of a glass substrate. First surface mirrors differ from second surface mirrors in that light does not have to travel through the glass before being reflected. This eliminates ghost images and makes first surface mirrors the superior choice for optical applications involving imaging.

Hi, I’m Emma, and welcome to our hand-picked collection of lightweight, comfortable, and stylish magnifying reading glasses, sunglass readers, protective magnified readers, multifocal reading glasses, and myopia distance glasses for short-sightedness. We also have a range of glasses cases and chains, straps and cords.

First surface optical mirrors may be fabricated with or without a protective overcoat. The choice depends on the reflectivity required for a specific application and the environment in which the mirror will be placed.

Standard protected aluminum (PAL) is one of our most popular coatings for the visible spectrum. A layer of Al is applied directly to the polished surface and then a thin layer of either SiO or SiO2 is applied. The overcoat provides protection for the soft aluminum layer underneath, allowing the mirror to be gently cleaned using proper optical techniques. Please see our page on How to Properly Clean an Optical Mirror for further information.

Advanced Optics manufactures bare aluminum and bare gold mirrors in almost any configuration to meet your requirements. For further information on our manufacturing capabilities, please visit our Capabilities page.

Aluminum and gold are the most common metals used without a protective overcoat. The bare (unprotected) metal provides a higher reflectivity than its protected (overcoated) counterpart. However, bare aluminum and bare gold are soft and should not be touched or cleaned. Therefore, careful consideration should be taken when choosing the type of metal coating for your application and whether or not a protective overcoat is required. Please visit our technical coating page for detailed information and technical coating curves for our bare aluminum and bare gold coatings.
