Optical glass is a type of glass specifically designed for use in lenses and other optical devices. It has unique properties that allow it to transmit light with minimal distortion, making it ideal for applications in cameras, microscopes, and telescopes. The composition of optical glass often includes various additives to enhance its clarity and refractive index. Manufacturers produce different grades of optical glass to meet specific requirements, such as crown glass and flint glass. These types vary in their ability to bend light, which is crucial for creating high-quality images. Optical glass plays a vital role in many technologies that rely on precise light manipulation.
