Scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens ...

An achromatic cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point-focusing spot ...

The achromatic LC lens system can be achieved by simply stacking these three LC components together. Both achromatic grating and deflector systems can be constructed based on the same principle.
