When developing an inspection system for PV (photovoltaic) solar-wafer, solar-cell, and FPD (flat-panel display) products, developers need to choose the type of camera lens that is most appropriate ...

One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be ...

Solar cells are an increasingly important source of renewable energy, but there’s still room for improvement. Stanford engineers have now developed a pyramid-shaped lens that can focus sunlight from ...

An innovative deep-space concept that relies on a solar gravity lens (SGL) to enable enhanced viewing of exoplanets is under study by researchers at NASA’s Jet Propulsion Laboratory (JPL) and The ...
