The design of our Enhanced Aluminum Mirrors

All of our SEA enhanced aluminum mirrors are protected by a multilayer dielectric overcoating. These very thin coatings considerably enhance the Enhanced aluminum front surface mirror opticsvisible reflectivity compared to bare aluminum or protected aluminum metallic mirror coatings and shield the metallic aluminum layer to prevent oxidization. The coatings are vacuum deposited on a high-grade glass substrate material. Because the optically effective mirror coating is located directly on top of the glass substrate, an excellent image quality is achieved by our enhanced aluminium mirrors. Ghost images or doubled laser beams, which are inherent to the functional principle of backside coated mirrors, are completely avoided with our front surface coated aluminum mirrors.

 

Properties, cost and applications

Both, the SEA-VIS and the SEA-NIR enhanced aluminum metal coatings show a good resistance to heat, humidity and abrasion which is much better than what can be achieved with silver mirrors. The mirrors are economically priced optics, which have proven to be an ideal choice for projects that require good optical performance, and a high mechanical stability at low cost. Therefore many high volume devices are based on our aluminum coated mirrors. The SEA-NIR near infrared aluminum mirror coatings also are an economically priced alternative to gold mirrors, when used as NIR or IR mirrors. For ultraviolet applications, we manufacture the protected aluminum SEA–UV mirrors. The SEA–VIS and SEA–NIR enhanced aluminum mirrors can be used as laser mirrors for up to medium laser beam powers. Please contact us and we will check whether our standard SEA mirror products can be used with your laser application without modifications. We manufacture all of our metallic aluminum front surface mirrors at large dimensions. The dielectric over coatings can be optimized and modified to enhance the reflectivity of special wavelengths. If you need a custom coating design, please use our coating enquiry page. If you have any special question, please contact our engineers for support in the design of your specialized enhanced aluminium mirror optics.

 

Where is the shopping cart?

You might wonder, why you will not find a shopping cart anywhere on our website. The simple answer is we just don't need a cart: The typical lead time for custom sized mirrors and many other optical components is less than a week, even at higher quantities, because we specialized in rapid manufacturing of custom mirrors and optics. We even offer a 48h Express optics service for a manufacturing and delivery of optics within only 2 working days. This is shorther than it ususally takes just to receive a quotation within the optics business and it is even faster than many catalog based companies can deliver their standard optics! So, no need for a shopping cart and pre-defined catalog sizes.
