Edmund Optics has introduced TechSpec spherical aberrationcompensation plates optimized for use in collimated light with small fields ofview. Leveraging a precision BK7 substrate, these ...

This breakthrough, which the team is calling the first broadband transformation optics metasurface lens, may lead to the creation of new types of antennas that are flat, ultra low-profile or conformal ...

Normal degrees of spherical and aspheric IOL tilt and decentration did not adversely affect optical quality, a study showed. “Tilt and decentration of IOLs implanted in the capsular bag in eyes with ...

To study the correlation between higher-order wavefront aberrations and visual function in eyes with a spherical monofocal intraocular lens (IOL), and to see if the aberrations differ between eyes ...

Aspheres allow designers to build smaller, lighter and simpler optical systems, and can be found in everyday products. Edwin Diaz provides a back-to-basics guide to the technology. You may not realize ...
