It is a hard optical glass with an Abbe number of around 50 to 60. Due to this low refractive index and low dispersion, crown glass is used to produce achromatic lenses. Flint glass is a very clear and highly transmissible glass, commonly used for lenses and prisms. WebJul 7, 2024 · What is combination of prism? When white light passes through a prism , it disperses into band of seven colours. But when two prism are combined in such a way that sum of angular dispersions of crown glass prism and flint glass prism is zero then such a combination is achromatic combination of prisms. 4-2-3-1 formation fifa
