Are you interested in optical coating but have no idea what it is all about? You came to the right place. In this article, we will discuss some of the most common uses of optical coating.
Optics as well as optical parts tend to be covered with a fine coating of material so that they will be able to adjust the lighting mirrored or released. Such coating material is known as an optical coating. Optical coating has a lot of applications, from light bulbs, to camera lens, mirrors, glasses, prisms, and more. The main function of optical coating is to obstruct specific wavelengths of lighting or to supply a very reflective surface area. There are some optical coatings that provide both of these functionalities, allowing certain wavelengths to be reflected, while blocking others. These kinds of optical coatings are of course more expensive compared to single function ones.
Products that Use Optical Coatings
- Camera lens
camera lens are the most prevalent users of optical coating. The lens of a camera is coated with a dielectric finish, providing a coating with anti-reflection properties. Dielectric coating is made up of calcium fluoride or magnesium flouride, or any other comparable materials. Dielectric coating enables the precise selection of structure of the lighting that enters the lens of the camera. As an example, dielectric coating is able to reduce the glare. They are also able to improve specific colors or wavelengths by limiting other colors.
- Vanity mirrors
Mirrors employ a reflective finish, which is usually a refined, ultra-thin metallic coating. The most common materials for mirrors are aluminum and silver because they are very reflective. If silver is used, the coating is done using silver vapor. When silver is used as the reflective, the achieved reflection is generally altered because silver is known for its limited reflectivity on some lights. Highly reflective materials can generally reflect light at greater than 99 percent ratio.
- Other applications of optical coatings
Optical coatings have a lot of some other applications, especially in the industrial sector. Equipment such as lasers, optical cables, and beam splitters utilize optical coatings to be able to properly function. Materials used for optical coating
There are more materials used for optical coating other than the aforementioned silver and aluminum. Nickel, copper, gold, and titanium are also used, and there are also multiple layer coatings as well, as stated earlier in this article. Multiple coated layers are great for custom applications since they are able to combine blocking lights and enhancing specific colors, depending on what is needed to be done. Certain coatings can be added for decorations too, such as highly reflective coating, and colored coatings. Lastly, there are coating that provides protection against infrared and heat.
