  • Patent number: 10663701
    Abstract: To provide an aspheric cemented lens which is easy to design and manufacture and has less aberration by using an inexpensive material such as a resin material. The aspheric cemented lens has at least three interfaces, when three interfaces are defined as a third interface, a second interface and a first interface in order from a light exit surface, chromatic aberration is corrected at the first interface and the second interface. The third interface is a hyperboloid or a surface close to a hyperboloid. When light is incident on the first interface parallel to the optical axis, the exit light from the third interface is converged to almost a single point. In order to correct chromatic aberration, the first interface and the second interface are curved surfaces.
