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 ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

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 ...
