Our enhanced aluminum front surface mirrors are our best-selling optical mirror products. They offer outstanding reflectivity and optical quality at an excellent price-performance ratio. Their aluminum coating has a dielectric multilayer overcoating on top to significantly increase the reflection in the design wavelength range. These overcoatings also protect the metallic aluminum layer from oxidation, scratches, and environmental influences.
Both the SEA-VIS and SEA-NIR mirror optics achieve outstanding imaging quality because the reflective coating is deposited directly on the front surface of a flat, mirror-quality substrate. Light sources, an image, or lasers do not have to travel through a glass twice to be reflected, as is the case with ordinary mirrors with a coating on the back. Ghost images, or the formation of phantom laser beams as it typically occurs with conventional mirrors, are thus eliminated.
The SEA-VIS mirrors are economically priced optics optimized for visible wavelengths. They are ideal for projects that require high optical reflectivity, excellent imaging precision, flatness, and good mechanical stability at a reasonable price. This makes the SEA-VIS the perfect front surface mirror for large-scale series.
The SEA-NIR mirrors have basically the same design concept as the SEA-VIS, except that the overcoating on top of the aluminum is optimized for high reflection of near-infrared wavelengths. Hence, the SEA-NIR is also often used as an alternative to gold-coated mirrors in the IR wavelength range.
All SEA mirrors can reflect lasers up to a certain energy density. Please contact our engineers to find out if you can use our SEA-enhanced aluminum mirrors in your laser application. Furthermore, we can adapt the overcoating to increase the reflectance for specific wavelengths or a broader wavelength range.

Standard fixed sizes are rarely an optimal solution, which is why we specialize in the rapid production of customized, enhanced aluminum mirrors. You can order exactly the rectangular or diameter mirrors that fit your specific application. Short lead times are also available for larger quantities, as our company is specialized in rapid serial production. We even offer our 48-Hour Express Service for the manufacturing and delivery of most of our standard materials in as little as two business days! This is less time than it typically takes to get a quote in the optical industry. It is often even faster than off-the-shelf catalog items are shipped. For this reason, we have deliberately refrained from implementing a shopping cart.
Besides the mirrors on this page, we provide metallic and dielectric mirror optics for many other optical tasks. If you are looking for UV front surface mirrors capable of reflecting ultraviolet light, please visit our SEA-UV data sheet.
