Aspherical lenses are lenses that continuously change the curvature in the radial direction.
Aspherical lenses are lenses that continuously change their curvature in the radial direction. This allows for the correction of spherical aberration (blurring of light), which would require multiple spherical lenses, with just one lens, and enables the realization of short focal lengths. Sankei Co., Ltd. has achieved a shape accuracy of 0.1 to 1 μm or less in mold processing to accommodate the plasticization of these aspherical lenses. Furthermore, thanks to accumulated know-how, we have achieved mass production. For more details, please contact us or refer to our catalog.
