Optical glass is a type of glass specifically designed to transmit light with minimal distortion. It is used in various applications, including lenses for cameras, microscopes, and telescopes. The quality of optical glass is measured by its clarity, refractive index, and ability to minimize imperfections. This glass is often made from silica and other materials that enhance its optical properties. Different types of optical glass can be produced to achieve specific characteristics, such as crown glass and flint glass. These variations allow for the creation of high-quality lenses that improve vision and image clarity in optical devices.
