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 lens adhesive lens, also known as achromatic lens, is made up of two single lenses bonded together, and its performance in multi-color (white light) imaging is much better than that of a single lens. 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, and so on. Lens materials include various high-quality glasses such as BK7, K9, quartz, germanium, silicon, zinc selenide, magnesium fluoride, etc. Lenses usually require anti reflective coatings to reduce surface reflection, which can reduce light energy loss and achieve clearer imaging.
