The enhanced aluminum mirrors of our SEA-VIS and SEA-NIR series are protected by reflection-increasing dielectric thin-film layers coated on top of a highly reflective metallic coating. These very thin overcoatings considerably improve the reflectance compared to bare aluminum and protected aluminum mirrors and protect the metal coating of the optics from oxidation and scratching. Both, the SEA-VIS and the SEA-NIR coatings show much better resistance to humidity and abrasion than silver mirrors.
The aluminum coatings of the SEA-mirrors are vacuum deposited to a high-grade glass substrate material. Because the optically effective mirror coating is located directly on top of the glass substrate, our enhanced aluminum mirror achieves an excellent optical imaging quality. Ghost images or phantom laser beams which both are inherent to the functional principle of backside coated mirrors are completely avoided with our enhanced aluminum front surface mirror optics.
The SEA-VIS mirrors are economically priced optics. Therefore, these coatings are the best choice for high volume applications. They have proven to be an ideal choice for projects that require good optical reflectivity and imaging performance in the visible wavelength area and high mechanical stability at a reasonable cost.
We have optimized the SEA-NIR mirror coatings for applications using near-infrared wavelengths. Hence, these optics are also a cost-effective alternative to gold-plated mirrors for the reflection of light energy in this wavelength spectrum up to the IR.
For ultraviolet and broadband UV-VIS-IR applications we have developed our SEA-UV-protected aluminum mirror (separate data-sheet) which only has a thin protective SiO2 (quartz) coating on top of the metallic aluminum thin-film.
The SEA mirrors can be used as laser optics for beams with up to medium laser power. Please contact us to learn whether you can use our standard SEA aluminum mirror coatings with your laser beam without modifications.
We can manufacture all of our aluminum front surface mirrors at large dimensions. If required, the protective overcoating layers can be optimized and modified to enhance the reflectance of the metallic coatings for particular optical wavelengths. In case you need optics with such individually adapted optical coatings please use our coating inquiry-form.

Where is the shopping cart?
You may be wondering why there is no shopping cart on our website. There is a good reason for this: Since every application requires different dimensions and our typical delivery time for individually dimensioned optical mirrors and many other optics is less than a week, we have refrained from limiting ourselves to standard dimensions. A shopping cart for a few standard products with few fixed dimensions which rarely represent an optimal solution for our customers therefore makes no sense for us.
Such short lead times are also possible for larger quantities as our company has specialized in the fast production of mirrors and optics with custom dimensions. Furthermore, we offer our 48 h express service for the manufacturing and delivery of custom-sized optics within only two working days. This period is shorter than it usually takes to just receive a price quotation for custom sized optics in the optical industry and this is quicker than many retail companies can ship their catalog optics with fixed dimensions. So the shopping cart is no advantage if you quickly need optics that perfectly fit your needs.
