What is an optical mirror?
Optical mirror is a mirror type used to reflect visible light in optical devices such as cameras and binoculars. These tools usually use an optical mirror to filter out the harmful effects of the reflected light or to send the light viewed to the eyepiece and work tool without distortion. These mirrors are also common in areas where endless space is needed for the light beam; Two mirrors can be set in parallel with each other so that the light can bounce forever and forth.
The production process for an optical mirror usually begins with a leaf of glass or plastic. Glass is generally a preferred basic material, but some applications require denser or more thermal resistant material, so instead of plastic. If the mirror needs a specific shape, it is usually formed, while it is still a leaf that prevents damage to the discouraging surface.
After the correct shape of the pane, one side of the panel is covered with a reflective substance. Historical, it wasN, mercury or silver, but today aluminum is the most commonly used reflective substance. Mirrors with specific light reflective properties, such as those used for scientific experimentation, are coated with any number of other chemicals, each with its own individual properties.
The quality of the optical mirror is often very easily tested. If a small item, such as a finger or an end and an uninhabited pencil, touches on the glass, reflects the overall surface quality. The distance between the actual and reflected picture shows the depth of the glass; The ghost image suggests that the pane is probably made of plastic or poor quality glass and any color change indicates a bad reflective coating. A good mirror will have a noticeable thickness and no variant or spirit.
The primary purpose of the optical mirror is to reflect light, but that's not all it does. Mirrors with specific reflectionWith a coating, they can filter out a certain wavelength of light, which is safer to observe. In addition, a set of properly aligned mirrors can divide the visible light into two different directions. This allows one to observe light while bringing light into a central tool like a camera.
people use optical mirrors for any number of reasons. Almost all personal mirrors such as bathroom or cars mirrors are a type of optical mirror. These mirrors are common inside non -diameter cameras, microscopes and binoculars, as well as almost any other device with a standard eyepiece. They are also used in almost any laser device, from a regular laser indicator to military sighting systems.
