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 ...

The solar gravitation lens (SGL) has much potential as a telescope. This point in space, located about 650 AU away from the sun, uses fundamental properties of physics to amplify the light from ...

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 ...

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 ...

Stacks of teeny lenses that look like inverted pyramids could juice up solar panels, helping them capture more light from any angle on both sunny and overcast days. Solar panels perform best in direct ...

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 ...
