Cemented lenses, also known as achromatic lenses, are made by bonding two single-element lenses together, and their performance in broadband (white light) imaging is much improved compared to single lenses. Achromatic lenses are made by bonding two lenses of different materials together, correcting the chromatic dispersion. Eliminating the problem of chromatic aberration, achromatic lenses have been widely used in multi-color lighting and imaging, improving cost-effectiveness.
