Invasive plant species can quickly overtake and eliminate native
plants in an area. To battle and control these invasions, you first
need to identify the invasive species, distinguish it even as an
immature plant from native species, and map its distribution
throughout an area.
The PSR+ and the RS-3500 spectroradiometers from Spectral
Evolution are field systems that can quickly help identify different
plant species to separate the native from invasive species using NIR
spectroscopy. By measuring absorbed and reflected light, each plant
produces its unique spectral "fingerprint."
Equipped with our unique leaf clip, these instruments can be used
for rapid field sampling. The spectroradiometers are fast and run off
a lithium-ion battery. Two batteries are provided for about 6 hours of
continuous scanning. The spectroradiometers are high
resolution/high sensitivity instruments designed for field use. They
are lightweight, rugged and reliable with no moving optical parts to
break or misalign. The leaf clip has a separate light source that is
kept away from your sample so there is no affect on the sample
during scanning. The light source, an ILM-105, is attached to the
spectroradiometer using a rail system and keeps heat away from the
leaf clip itself.
The leaf clip has a built-in white reference and a swivel head. Just
squeeze the handle and insert the sample into the clip. The PSR+ can
also be used with direct attach lenses for standoff measurements.
The PSR+ and RS-3500 can also be equipped with field-of-view (FOV)
lenses and a pistol grip, a benchtop probe for crushed samples, soil,
or powders, or a contact probe.
Both spectroradiometers are available with EZ-ID sample
identification software that allows you to build your own custom
library. By identifying different invasive species at different stages in
growth, you can compare samples to your library for fast
identification and eradication. In addition you can check the health
and monitor the growth of native species affected by the invasion./
Designed for field use with solid state photodiode arrays and no moving
optical parts, the PSR+ and RS-3500 spectroradiometers are ideal for in situ
scans and fast species identification.
Our unique leaf clip is well-suited for species identification. A white reference panel
is built into the swivel head. After taking the reference scan just turn to the black
side and insert the sample leaf. Scanning is quick easy and accurate. The light
source is positioned on the spectroradiometer via a rail system so heat and other
damage is kept away from the sample.

Field portable NIR spectroradiometers provide in the field
identification of plant species
With the optional EZ-ID sample identification software, you can build your own
library as you scan adding metadata such as plant name, species, operator,
location, etc. As well as up to 8 custom metadata fields. All data is saved as an
ASCII file for use with other analysis software.
