Best Choice of Spherical Lens

According to the refraction of light and Snell's law, light will be refracted at the interface between the optical material and the air, resulting in a change in the direction of light propagation. Parallel rays of light converge to a point after passing through a double-convex lens and plano-convex lens. They diverge after passing through a double-concave lens and plano-concave lens
