epitex® Spectro Series LEDs

Ushio Opto-Semiconductors, Inc. has developed a broadband LED that produces the world’s maximum output of 160 mW between 400 and 1000nm, covering the range from visible light to near-infrared light.

Available with a variety of packaging options, this LED uses a fluorescent material featuring a continuous spectrum, making it advantageous for use in the following applications:

• Agricultural and bio-medical: determining the type and amount of a substance (e.g. sugar content or blood oxygen saturation level)
   
  Well-suited because: the absorption characteristics of near-infrared light differ from one substance to another; can meet demand for smaller/portable measuring devices

  ---

• Sorting and recycling: e.g. material, color, and other properties of PET bottles
   
  Well-suited because: light source can be combined with a photodetector

  ---

• Light source: improves options for miniaturization
   
  Well-suited because: can use one device and avoid installing multiple devices to measure different materials (since conventional near-IR LEDs provide monochromatic light from one device); removes adjacent heating issues from halogen sources, which require a heat dissipation jig that can prohibit size reduction

  ---

• Light source: improves options for longevity
   
  Well-suited because: improved output power compared to other wide wavelength-range LEDs; avoids short lifetime of halogen sources that require frequent replacement
