L-3 AOC Develops Enhanced Gold Coatings for Large-Format Substrates

Facebook X LinkedIn Email
L-3 Applied Optics Center (AOC), part of L-3 Communications Warrior Systems, has developed a line of gold optical coatings for large-format substrates, offering custom wavelength-specific performance.

The thin-film gold optical coatings are suitable for deposition on lightweight optical elements for applications where weight and performance are critical design factors, such as terrestrial and airborne imaging systems. They work with optical elements in excess of 350 mm in diameter.

Other products currently in development include highly-specialized reflective metallized films such as protected silver, aluminum and silicon carbide, and a range of metal oxides for commercial and military applications.

Glossary
optical coatings
Optical coatings are thin layers of materials applied to optical components, such as lenses, mirrors, filters, and prisms, to modify their reflective and transmissive properties. These coatings are designed to enhance the performance of optical systems by controlling the way light interacts with the surfaces of the components. The primary purposes of optical coatings include: Antireflection coating: This type of coating is designed to reduce reflections from the surfaces of optical...
thin film
A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
wavelength
Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
