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