Color-Changing Surface Tunable Through Electrical Voltage
Video screens are made up of hundreds of thousands of pixels that display different colors to form the images. With current technology, each of these pixels contains three subpixels — one red, one green, and one blue. A new method was developed to tune the color of the subpixels. The new...
Products: Sensors/Data Acquisition
The BGA244 Binary Gas Analyzer from Stanford Research Systems, Sunnyvale, CA, continuously and non-invasively determines the ratio of gases in a binary mixture, or checks the purity of a single gas. It operates without...

Dual-Field-of-View Multiband Optics
Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...
