How do you find the quality of the light a light bulb produces? Using the color rendering index, a measure of how well a light bulb illuminates a range of colors. Appliance Science looks at the ...

Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology ...

Originally setting out to design safety glasses for use during laser surgeries, materials scientist Don McPherson instead designed a lens that enables color-blind wearers to see the full light ...

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of ...
