What is another word for optical flint?
Pronunciation: [ˈɒptɪkə͡l flˈɪnt] (IPA) 
Optical flint is a type of glass that has high refractive index and dispersive power. It is used extensively in the manufacturing of lenses and prisms. There are several synonyms for optical flint, depending on its composition and intended use. Some of these synonyms include crown glass, which has a low refractive index and is used in the production of simple lenses. It also includes dense flint glass, extra dense flint glass, and ultra-dense flint glass, which have higher refractive indices and are used in the manufacturing of complex lenses and prisms. Other synonyms include lead glass, borosilicate glass, and Schott glass. Each of these types of glass has unique properties that make it ideal for different applications in optics.
