As anyone who has recently tried out an augmented reality headset knows, the technology is not yet ready to be part of our everyday lives. Researchers have been working to perfect high-performing ...

Optical flats are single precision flat surfaces. They are used as reference surfaces to compare flatness of a substrate where flatness is unknown. When a high quality optical flat is placed on top of ...

Manufactured using optical fused silica for extra thermal stability, the 1/20 Wave Tech Spec optical flat mirror is available coated or uncoated. The mirror's primary surface is precision ground and ...

Columbia engineers invent a flat lens that exclusively focuses light of a selected color—it appears entirely transparent until they shine a beam of light with the correct wavelength onto it, when the ...
