INNOVATION A dual UV/Vis
spectroradiometer designed for underwater
measurements of apparent optical properties of
sea water.  The high-speed dual-spectrometer
design allows reasonable sounding rates while
providing simultaneous up- and down-welling light
measurements.  The use of a high spectral
resolution spectrometer overcomes the limitations
of filter-based designs.

• ACCOMPLISHMENTS
• Successful development of a high-speed,
  high-spectral resolution solid state spectrometer
  module.
• Delivery of an operational system meeting design
  specifications.
• COMMERCIALIZATION
• The design and manufacture of spectrometers is
  ASD's main business. Several of the key
  components developed as a part of this SBIR have
  been incorporated into ASD's standard
  spectroradiometer product line (spectrometer
  module, analog spectrometer module interface, and
  DC power system).
• A non-submersible version of this instrument, the
  FieldSpec VNIR-Dual, has been developed and is
  commercially available.  The FieldSpec VNIR-Dual
  is used by more than 25 research institutions in
  both the U.S. and overseas.

• GOVERNMENT/SCIENCE APPLICATIONS
• High-spectral resolution measurements of apparent
  optical properties of seawater are essential to
  several NASA, ESA and NASDA oceanographic remote
  sensing programs. NASA, NASA-funded, and other
  researchers are using the instrument developed
  for this SBIR and the FieldSpec VNIR-Dual,
  derived from the technical advances made during
  this SBIR, to perform these essential
  measurements.
