It can reduce chromatic aberration and spherical
aberration to a large extent, and can better focus the incident light into a
line. Compared with single-piece lenses with equal diameter and focal length,
achromatic lenses have significant advantages. It is more suitable for
broadband light sources to reduce chromatic aberration to a large extent, and
can produce concentrated lines with less dispersion or clear irregular-shaped
images. It is widely used in laser shaping, laser projection and other related
fields
