Cemented Lens

The cemented lens is also called an achromatic lens. It is formed by cementing two single lenses. The imaging performance in the polychromatic (white light) is much higher than that of a single lens. The achromatic lens consists of two lenses of different materials glued together to correct the dispersion of the glass. Eliminating the problem of chromatic aberration, achromatic lenses have been widely used in multi-color lighting and imaging, which improves cost-effectiveness.
