Fluoride glasses are a type of optical glass that contain fluoride ions, which enhance their properties. These glasses are known for their low refractive index and high transmission of infrared light, making them useful in various optical applications, such as lenses and prisms. Their unique composition allows for better performance in specific environments compared to traditional silicate glasses. Due to their special characteristics, fluoride glasses are often used in advanced technologies, including fiber optics and laser systems. They are particularly valuable in scientific research and industrial applications where precise light manipulation is essential.
