About Raster Orbital Scanning (ROS)
The Ocean Optics IDRaman mini uses ROS to rapidly scan a tightly focused beam in an orbital pattern,
allowing lower average power to produce high-integrity data from a larger area of the sample without
sample ignition or damage.
A tightly focused beam may result in noisy signals
or missing the Raman active target completely,
leading to false negative readings from unidentified
samples.
Increasing the spot size of the laser dilutes the
valuable information about the material, leading to
inconclusive matches or false identification of
samples.
ROS increases the effective size of a tightly
focused beam. Information is obtained with
complete integrity while sampling the large area
needed for complex mixtures or irregularly shaped
samples, leading to confident identification.
