  • Patent number: 8749892
    Abstract: A wide field angle camera module that incorporates field curvature correction suitable for an electronic device is described herein. By way of example, the wide field angle camera module comprises micro optical lenses adapted to capture field angles of greater than thirty degrees, and is further adapted to provide field curvature correction for a range of object distances, and for a range of zoom configurations include 1×, 2× and 3× zoom configurations. Furthermore, the field correction can be implemented alone or in conjunction with signal processing that corrects barrel distortion introduced by the micro optical lenses. In particular aspects, the field correction can be automated based on image quality analysis to provide a high quality image for object distances substantially 30 centimeters or larger.

  • Patent number: 7982969
    Abstract: A projection objective of a microlithographic projection exposure apparatus has a high index refractive optical element with an index of refraction greater than 1.6. This element has a volume and a material related optical property which varies over the volume. Variations of this optical property cause an aberration of the objective. In one embodiment at least 4 optical surfaces are provided that are arranged in at least one volume which is optically conjugate with the volume of the refractive optical element. Each optical surface comprises at least one correction means, for example a surface deformation or a birefringent layer with locally varying properties, which at least partially corrects the aberration caused by the variation of the optical property.
