In the past, when manufacturing mirrors, silver was often plated on glass. The standard process for making it is: vacuum evaporating aluminum on a highly polished substrate, and then plating with silicon monoxide or magnesium fluoride. In special applications, it is caused by metal. The loss can be replaced by a multilayer dielectric film. Because the law of reflection has nothing to do with the frequency of light, this kind of element has a wide working frequency band, reaching the ultraviolet and infrared regions of the visible light spectrum, so its application range is becoming wider and wider. On the back of the optical glass, a metal silver (or aluminum) film is coated by vacuum coating to reflect the incident light. The use of a high reflectance mirror can double the output power of the laser; and it is reflected by the first reflecting surface, the reflected image is not distorted, and there is no ghosting, and it is the reflection of the front surface. If an ordinary reflector is used as the second reflecting surface, not only the reflectivity is low, the wavelength is not selective, but also the ghost is easy to produce. However, the use of a coated film surface reflector not only has high brightness, but also is accurate and unbiased, the picture quality is clearer, and the color is more lifelike. The front surface mirror is widely used for optical high-fidelity scanning reflection imaging.
