Ultrasensitive Mini-Spectrometers

Researchers have developed a multi-channel, ultra-sensitive optical spectrometer that combines the advantages of a compact size and short sapling time with higher sensitivity (50- to100-fold) over CCD-array-based detectors currently on the market, which allows for measurements of substances at much lower concentrations than is now possible. This opens the door to several new markets for spectrophotometers.

Miniature optical spectrometers based on linear silicon CCD array detectors have been around for decades and have several advantages over conventional desk-top scanning: compact size, robust optoelectronics, and short sampling time. However, the sensitivity of the CCD-array-based spectrometer is low.

This new mini-spectrometer can bring the power of benchtop dectection instruments into the hands of first responders, TSA agents, field researchers, and others.

BENEFITS:
  • Compact Size, Portable
  • Robust Optoelectronics
  • Short Sampling Time
  • Ultrasensitive Detection
  • Inexpensive to Produce

POTENTIAL APPLICATION:
  • Field Research
  • Emergency Response
  • Security (airports, etc.)
  • Environmental Control

DEVELOPMENT STATUS:
  • Ready for Prototype Development or Retrofitting to Current Devices
