"Aluminum mirrors" are general mirrors that reflect light across a wide range of wavelengths. Due to their delicate low-hardness film, they are often protected by SiO films, and deposition is possible not only on glass substrates but also on aluminum and resin. Additionally, "aluminum enhanced reflective mirrors" are mirrors that further increase the reflectivity for specific wavelengths by adding a dielectric multilayer film to the aluminum film, which also contributes to the durability of the aluminum film. 【Features of Aluminum Mirrors】 ■ Delicate film with low hardness ■ Deposition is possible on aluminum and resin as well as glass substrates *For more details, please refer to the PDF document or feel free to contact us.
