This story follows the moment a scratch-built pinhole camera stopped being a rough experiment and started producing real, ...

Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...

If you’re having trouble finding NASA-approved eclipse glasses online or around town, you’re not alone. Local retailers are running out of stock ahead of the much-anticipated Great American Eclipse ...
