One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

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

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 ...

Aspheric lenses are designed to focus or collimate light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents ...
