The achromatic Spherical Lenses have a crescent shape (concave and convex) and are cemented by two lenses with different refractive indexes and dispersion rates. It can correct the chromatic aberration of the light of the lens group of three wavelengths (blue, green and red). Since the blue image of the light condensed by the Plano Convex Lens has a close focal length, and the concave lens has a high divergence rate for blue light, the chromatic aberration of the two mirrors is opposite, so that the red and blue images can be superimposed into one, and the chromatic aberration is basically eliminated. The crescent surface can limit spherical aberration and coma. But there is astigmatism and distortion. In the early days it was mostly used to shoot landscapes, hence the name landscape lens.
