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.

The role of laminated lenses in optical systems is to focus, collimate, and image. Depending on the surface shape of the lens, there are: plano convex, plano concave, biconvex, biconcave, meniscus, laminated mirror, etc. Lens lenses usually require coating with an anti reflective film to reduce surface reflection, which can reduce the loss of light energy and result in clearer imaging.
