What Is a Enhanced Aluminum Mirrors?

Enhanced aluminum mirrors use a multi-layer dielectric overlay on aluminum to boost reflectance in the visible spectrum above standard aluminum coatings. They offer R > 92% across 400-800nm while maintaining good UV extension.

Ideal for general laboratory mirrors, visible laser alignment, imaging relay systems, and applications requiring better visible performance than standard aluminum at moderate cost.

Optical Coating Options

Enhanced Aluminum

Multi-layer overcoat on Al. R > 92% (400-800nm).

Typical use: Visible broadband applications

How to Specify Your Coating

To select the right coating, please provide: (1) Operating wavelength, (2) Angle of incidence, (3) Required transmission or reflectivity, (4) Laser power density (if applicable), (5) Operating environment.

Engineering Considerations

Key factors to evaluate when specifying this optical component for your system.

Reflectance

R > 92% in visible, dropping in UV and NIR. Verify spectral requirements.

Durability

Protected overcoat extends lifetime but not as durable as dielectric.

AOI

Non-normal AOI causes S/P polarization differences. Specify your angle.

Cleaning

Use compressed gas first. Avoid aggressive solvents on protective overcoat.

Applications

Laser Systems

Beam delivery, focusing, and conditioning for industrial and scientific laser systems.

Semiconductor

Wafer inspection, lithography support, and process control optics.

Machine Vision

Image formation in inspection systems and quality control cameras.

Research & Education

Laboratory optics, teaching setups, and experimental beam paths.

Frequently Asked Questions

What reflectivity can I expect?

Reflectivity depends on the coating: Protected Silver > 97% (400-2000nm), Protected Al > 90% (250-2000nm), Dielectric HR > 99.9% at design wavelength.

What is the laser damage threshold?

LIDT depends on coating type. Dielectric HR coatings typically have the highest LIDT. Specify your laser parameters for proper coating selection.

What substrates are available?

Standard substrates include BK7, UV Fused Silica, and Float Glass. For IR applications, we offer Cu, Mo, and Si substrates.

Can mirrors be used at non-normal incidence?

Yes. Specify the angle of incidence (AOI) for proper coating design. S-polarization and P-polarization have different reflectance at oblique angles.

How should I handle and clean mirrors?

Handle by edges only. Use compressed gas for dust removal. For smudges, use optical-grade cleaning solvents with lint-free wipes. Avoid touching coated surfaces.

What is the lead time for custom mirrors?

Custom optics require engineering evaluation. Lead time is confirmed with your quotation.
