Optical Mirrors

Full Range High-Quality Flat Optical Mirror Solutions

Our flat optical mirrors offer a full range of solutions for reflecting light to optimize performance in the UV-VIS-NIR spectral regions. Advanced Optics precision polished flat optical mirrors are available in stock or can be fully customized to meet your unique requirements. We offer plane-parallel, wedged, or spherical optical mirrors manufactured from a wide variety of substrates polished in almost any configuration. All of our optical mirrors may be purchased uncoated or with a variety of metallic coatings, highly durable dielectric coatings, or as partially reflective mirrors.

Whether you require one of our many catalog mirrors or need a custom fabricated optical mirror, from prototype to production, let Advanced Optics be your trusted partner - You can depend on our 100% outgoing inspection, on-time delivery, and unmatched customer service, all at competitive prices.

Optical Mirror Manufacturing Proficiencies

  • Fabricate flat optical mirrors from 1mm – 530mm
  • Manufacture plane-parallel, wedged, or spherical optical mirrors
  • Precision polish round, rectangular, and square substrates with the capability to provide custom optical mirrors in almost any configuration to meet your requirements
  • Produce optical mirrors from a variety of substrates including fused silica, quartz, Zerodur®, BOROFLOAT®33, N-BK7® and soda-lime glass
  • Achieve parallelism of < 2 arc seconds and offer wedged mirrors

Available Precision Grade Optical Mirrors

Our in-stock precision 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 Ravg >85% from 400 – 700nm. They continue to provide good reflectivity into the NIR spectrum with Ravg >90% 400 – 2000nm making it an excellent choice for many broadband applications. Other metallic coatings, including custom coatings, are available upon request.

Available Commercial Grade 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 Ravg > 91% from 200 – 2000nm and Ravg > 96% from 2 – 10µm. Unlike protected aluminum (reflectivity data above), 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.

UV-VIS-NIR Optical Mirror Solutions

Our optical mirrors can be optimized to reflect light of specific wavelengths from the deep UV to the infrared. Advanced Optics manufactures a wide range of precision polished and commercial grade in-stock or custom optical mirrors to meet your exact requirements.

Optical Mirror Coating Capabilities
  • Offer substrates either uncoated or with a variety of reflective coatings optimized for performance in the UV-VIS-NIR spectral regions (190 - 2500nm) with the ability to provide highly reflective coatings out to 20 microns
  • Provide metallic, dielectric, and partially reflective coatings
  • Custom coatings available upon request
