    • An optical lens system that focuses both a first band of wavelengths and a second band of wavelengths onto a common focal plane. In some cases, the lens system includes a first region for focusing a first band of wavelengths onto a focal plane, and a second region for focusing a second band of wavelengths onto the same focal plane. Depending on the wavelengths and materials involved, the first region may or may not focus the second band of wavelengths onto the focal plane, and in some cases, may or may not even transmit the second band of wavelengths to the focal plane. Likewise, the second region may or may not focus the first band of wavelengths onto the focal plane, and in some cases, may or may not even transmit the first band of wavelengths onto the focal plane, but this is not required. In some embodiments, an additional lens may be provided between the lens system and the common focal plane to help focus the first band of wavelengths and the second band of wavelengths onto the common focal plane. The additional lens may be made from a material or material system that transmits and focuses both the first band of wavelengths and the second band of wavelengths.
    • 一种将第一波长波段和第二波长带聚焦在公共焦平面上的光学透镜系统。 在一些情况下,透镜系统包括用于将第一波长带聚焦到焦平面上的第一区域和用于将第二波长带聚焦到同一焦平面上的第二区域。 取决于所涉及的波长和材料,第一区域可以或可以不将第二波长带聚焦到焦平面上,并且在一些情况下,可能甚至不会将第二波长带透射到焦平面。 类似地,第二区域可以或可以不将第一波长带聚焦到焦平面上,并且在一些情况下,可能甚至不会将第一波长带传播到焦平面上,但是这不是必需的。 在一些实施例中,可以在透镜系统和公共焦平面之间提供附加透镜,以帮助将第一波长波段和第二波长带聚焦到公共焦平面上。 附加透镜可以由材料或材料系统制成,该材料或材料系统透射和聚焦第一波长波段和第二波长波段。
