• Provide metallic, dielectric, and partially reflective coatings
• Custom coatings available upon request

Our Technical Optical Mirrors page provides further information on our full range of mirror coatings.

Advanced Optics in-stock optical mirrors come standard with a protected aluminum coating. Protected aluminum mirrors are a popular choice for use in the visible spectrum due to their low cost and good reflectivity with R_avg >85% from 400 – 700nm. They continue to provide good reflectivity into the NIR spectrum with R_avg >90% 400 – 2000nm making them an excellent choice for many broadband applications. Other metallic coatings, including custom coatings, are available upon request.

In-Stock Commercial Grade Optical Protected Al Mirrors

• Protected Aluminum Commercial Grade Optical Mirror
• Protected Aluminum Coating Curve

Our commercial grade optical mirrors come with the same durable protected Al coating as our precision grade mirrors. These mirrors offer an excellent economical alternative to high-precision optics when the application is less demanding. In addition to our standard protected Al mirrors, we offer these mirrors with a variety of metallic coating including bare Al and bare Au.

Bare Aluminum Optical Mirrors

Advanced Optics manufactures both bare aluminum and protected aluminum commercial grade optical mirrors. Bare aluminum mirrors provide good reflectivity from the near UV to the IR spectrum, with R_avg > 91% from 200 – 2000nm and R_avg > 96% from 2 – 10µm. Unlike protected aluminum, bare aluminum is very soft, which makes these mirrors difficult to clean without damage, and they will oxidize over time. Therefore, bare aluminum mirrors are best suited for use in climate-controlled environments where they will be enclosed with limited handling. The benefit of a bare aluminum mirror is that it does not have a protective overcoat, which causes interference or absorption of light. This makes it the mirror of choice for some systems such as spectrophotometers.

In addition to our large variety of in-stock optical mirrors, Advanced Optics also offers custom optical mirrors and free engineering services. We have the capability to provide custom shapes, apply bevels and drill holes to meet your unique requirements.

Optical Mirror Design

For a first surface optical mirror to perform as expected, having a good understanding of your application (as well as specifying the correct optical characteristics) is essential to reducing costs and procuring the perfect mirror. Careful consideration should be given to the following and provided when requesting a quotation for an optical mirror.
