Learn how convex and concave lenses differ in shape, function, and application, and how they are used in optical engineering, especially in fiber optics.

Typical deflection sensors like strain gauges or devices based on optical fibers require physical contact with the deflected substrate during the measurement process. Such contact, however, impacts on ...

Curving a standard CMOS image sensor into a convex or concave shape could improve its imaging capabilities (Courtesy: Simona Lombardo) It’s not just televisions and smartphones that are looking ...
