Our SEA enhanced-aluminum-mirrors are protected by reflection-enhancing, dielectric thin-film layers, which are coated on top of the metallic layer. These very thin protective coatings considerably enhance the reflectance compared to bare or SiO2-protected aluminum mirrors and prevent the aluminum coating from oxidation.
The coatings are vacuum deposited on a high-grade glass substrate material. Because the optically effective mirror coatings are located directly on top of the glass substrate, our enhanced aluminum mirrors achieve an excellent image quality. A ghost image or a doubled laser beam, which are inherent to the functional principle of backside coated mirrors, is completely avoided with our front surface coated aluminum mirror optics.
Both, the SEA-VIS and the SEA-NIR enhanced aluminum coatings show much better resistance to humidity and abrasion than silver mirrors. The SEA-mirrors are economically priced optics, which have proven to be an ideal choice for projects that require a good optical reflectivity performance and a high mechanical stability at reasonable cost. Hence, many high volume applications are based on our enhanced aluminum metal-coated mirrors. The SEA-VIS coating is designed for applications in the visible spectrum. The SEA-NIR mirror coatings have been optimized for near infrared wavelengths. They can be a cost-effective alternative to gold mirrors, when used for the NIR or IR wavelength range. For ultraviolet applications and for broadband UV-VIS-IR applications, we fabricate our SEA-UV protected aluminum mirrors (separate data-sheet) which have a metallic aluminum layer and only a SiO2 layer coated on top.
The SEA-VIS and the SEA-NIR mirrors can be used as laser beam mirrors up to medium laser powers. Please contact us to check whether our standard SEA mirror coatings can be used with your laser beam without modifications.
We manufacture all of our aluminum front surface mirrors at small and large dimensions. If required, the dielectric overcoating layers can be optimized and modified to enhance the reflectance of the metallic coating for special wavelengths. In case you need such a custom coating, please use our coating enquiry-form to send a request.
If you have questions, you can find further information referring the SEA-VIS and SEA-NIR enhanced aluminum front-surface mirrors on our "Frequently Asked Questions" (FAQ) web page. For additional support in designing, please contact our engineers. We will be pleased to help you in development of your individual enhanced aluminium mirror optics.

You may be wondering why there is no shopping cart on our website. The simple answer is: we don't need one. The typical delivery time for custom mirrors and many other optics is less than a week. This is also possible for larger quantities, as our company has specialised in the fast production of mirrors and optics with custom dimensions.
Furthermore, we offer our new 48h express optics service for a manufacturing and delivery of cutom-sized optics within only 2 working days. This is shorter than it ususally takes to simply receive a price quotation in the optics industry. And this is quicker than many retail companies can ship their catalog products with fixed dimensions. So a shopping cart is no advantage if you need a part that perfectly fits.
