The SEA-VIS is the best-selling front surface mirror in our company's portfolio. It offers excellent reflection and high optical quality at a comparatively low price. Both enhanced aluminum mirror series, the SEA-VIS and the SEA-NIR, have a dielectric thin-film overcoating deposited on top of their highly reflective aluminum metal layer. This multi-layer overcoating considerably increases the optical reflectance over bare aluminum or protected aluminum mirrors and protects the metal coating from oxidation. Due to the thicker protective thin film coating, the SEA-VIS and the SEA-NIR mirrors show much better resistance to humidity, abrasion, and scratching than the sensitive coatings of protected aluminum or silver front surface mirrors.
The coating of the SEA mirrors is vacuum-deposited onto selected high-quality glass substrates. The mirrors achieve superior optical imaging accuracy because the coatings are coated directly on the front surface of a mirror-grade substrate. The light beam does not have to travel through the substrate glass twice to be reflected, as is the case with ordinary backside-coated mirrors. Hence, ghost images or the formation of phantom laser beams in the reflected image, which occur with backside-coated mirrors, are thus completely prevented.
SEA-VIS mirrors are economically priced optics. They are ideal for projects that require high optical reflectivity, imaging performance in the visible or near-infrared wavelength region, and high mechanical stability at a reasonable price. Therefore, the SEA-VIS is often the best choice for high-volume applications. We optimized the SEA-NIR mirror coating for the near-infrared wavelength region. Hence, they represent an economical alternative to gold-plated mirrors in this spectral range for many applications.
Further, we developed our protected aluminum SEA-UV mirror (separate datasheet) for ultraviolet wavelengths and broadband UV-VIS-IR applications. This mirror only has one thin protective SiO2 (quartz) layer on top of the metallic aluminum thin film to enable high UV reflectivity.
The SEA mirrors also work as laser mirrors for up to medium-power lasers. Please get in touch with our engineers to find out whether you can use our unmodified enhanced aluminum mirror with your laser application without modifications. We also fabricate our enhanced aluminum optical mirrors at large dimensions. Moreover, we can optimize and modify the protective overcoating layers to increase the reflectance for particular optical wavelengths if required. Please consider using our coating inquiry form to get a quotation for mirrors with individually adapted optical properties.

You may be wondering why there is no shopping cart on our website. Since every application requires different dimensions and our typical delivery time frame for individually sized optical mirrors and many other optics is less than a week, we have refrained from limiting ourselves to a few standard sizes. A shopping cart for a handful of items with limited fixed sizes does not make sense for a manufacturing company because it rarely represents an optimal solution for our customers.
Short lead times are also possible for more substantial quantities, as our company has specialized in the fast production of mirrors and other optics with individual dimensions. We even offer our 48-hour express service to manufacture and deliver custom-sized optics with stock thicknesses within only two working days. This period is shorter than it usually takes to receive a price quotation in the optical industry, and is quicker than many retail companies can ship their catalog stock optics with fixed dimensions. A shopping cart is no advantage if you quickly need optics that fit your needs perfectly.
