Introduction
Thank you for selecting the XDS™ OptiProbe
Transmission Analyzer, manufactured by FOSS. This
instrument is the third generation in a series of
instruments designed for precision NIR
measurement, characterization of organic
materials, and qualification of known materials to
quality parameters.
The XDS™ is designed for stable operation in harsh
environments, while still providing the precision
and accuracy users have come to expect of FOSS
instruments.
Standard fiber bundle length is 1.5-meters.
The OptiProbe Transmission Analyzer uses a proven monochromator design, employing a digitally-
controlled dispersive grating, along with sensitive detection devices and state-of-the-art circuitry to
enhance signal output and minimize any extraneous noise that might influence performance. The
XDS™ uses various patented algorithms to provide superior accuracy and transferability between like
instruments.
This instrument uses near-infrared (NIR) spectral energy to illuminate the sample. By measuring the
energy passing through the sample, chemical information and composition may be determined. This
information may be used for quantification of constituents, or for comparison to a library of known
materials, providing identification and qualification of materials.
The OptiProbe Analyzer has been a versatile, proven design for NIR sampling for many years. As an
XDS™ instrument, the OptiProbe benefits from the improvements in wavelength accuracy, precision,
low noise, speed, and overall performance.
A panel of 6 LED indicators provides information to the user on these functions:
Icon Status
Green when power is ON
Amber when connected to network or direct
connection
Green when instrument lamp is ON
Red when scanning reference or sample
