PASADENA, Calif., June 19, 2006 -- Viaspace Inc., a provider of hardware and software solutions involving energy/fuel cells, microelectronics, sensors, homeland security and public safety, announced today that it has acquired a 15 percent share in QWIP Systems Inc., a developer of quantum-well infrared photodetectors (QWIP), through a stock conversion. QWIP sensors are similar to the electronic sensors in digital cameras and camcorders, except they detect heat emissions rather than light. QWIP sensors are used in military and security applications because they can see in total darkness. Long-wavelength infrared sensors are...Read full article

    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
