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 ...

Sapphire crystal (Al2O3) is a sought-after substrate for a range of high-precision applications; for example, for aerospace and aeronautical vehicles and high-powered laser applications, such as Er: ...

Thirty patients were randomised to receive one of six lens implants including three aspheric lenses and their spherical counterparts. Pre and postoperative testing was carried out including visual ...

In the early 1990s, the Opticam ® SM machine was developed for use in the analysis of microgrinding at the Center for Optics Manufacturing, University of Rochester. In mid-1992, a multi-axis flexible ...

Filmmaker Ryan Freeman has asked the unaskable: can you compare a $30,000 Cooke anamorphic lens with a $1,000 Zeiss spherical lens? Well, to insert a bit of a spoiler here, no, you can't. Cooke makes ...

Camera lenses are often described as being 'aspherical', but what does it mean, and is it the only way to design a lens? A lot of lenses are spherical, though. What we mean by “spherical” is usually ...

A new breakthrough could soon revolutionize the design of almost every optical instrument in use today, including cameras, eyeglasses and telescopes. Combining recent developments in artificial muscle ...
