Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

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 ...

Slightly larger than a mobile phone, Ocean Optics' fiber-optic USB4000 spectrometer uses a 3648-element Toshiba linear CCD array detector and high-speed electronics. For the MARC system, the ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

While it's very important to track malaria infections in at-risk populations, drawing and analyzing blood samples can be problematic. A new device is designed to help, as it uses light to detect the ...

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...
