An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical coating is an antireflection coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and photographic lenses. Another type is the high-reflector coating which can be used to produce mirrors which reflect greater than 99.99% of the light which falls on them. More complex optical coatings exhibit high reflection over some range of wavelengths, and anti-reflection over another range, allowing the production of dichroic thin-film optical filters.

  • 光学薄膜(こうがくはくまく)とは、光路長 nd における屈折率 n を有する膜厚 d の蒸着薄膜のことである。
  • Un recubrimiento óptico es una capa fina de algún material concreto que se deposita sobre un elemento óptico, como una lente o un espejo, con el fin de alterar sus propiedades ópticas (reflexión y transmisión de la luz). Un tipo de recubrimiento óptico es el tratamiento antirreflectante, usado para evitar reflexiones no deseadas sobre superficies ópticas (como gafas u objetivos de cámaras). Otro tipo es el recubrimiento de alta reflexión, usado en espejos para mejorar sus propiedades ópticas y lograr que se refleje hasta el 99,99 % de la luz incidente. Otros recubrimientos ópticos más complejos permiten alcanzar una alta reflexión para longitudes de onda dentro del rango de paso, y el efecto opuesto para el resto de longitudes de onda, permitiendo de este modo la fabricación de componentes
