The NEW PSR+ Series of spectroradiometers features a new
standard for remote sensing applications in the field.
Our sleek, compact design results in an full range NIR
agricultural spectroradiometer that's easier to handle and
operate - there's no better instrument for field work whether you
are ground truthing satellite or flyover hyperspectral data,
engaging in vegetation studies, performing canopy research,
studying crop health and climate change, doing soil analysis -
potential applications are virtually endless.
The PSR+ not only looks and feels great, we've also enhanced
performance and reliability. System cooling has been enhanced
with the new unibody anodized aluminum chassis with integral
heat dispersion channels.
Our new proprietary Sotex™ filter technology delivers improved
order sorting for enhanced stray light performance and
smoother transition between detectors.
Spectral resolution for the PSR+ is enhanced for high resolution
- 3nm @ 700nm (FWHM)
- 8nm @ 1500nm (FWHM)
- 6nm @ 2100nm (FWHM)
Our signal-to-noise ratio is best-in-class and auto-shutter, auto-
exposure, and auto-dark exposure provide one-touch operation.
With no moving optical parts and an improved optical path it is
ideal for field use no matter what the conditions.
The PSR+ can be combined with a wide range of accessories,
including a range of FOV options such as direct attaching 4, 8, or
14° lenses, 25° fiber optic, diffuser, or integrating sphere. Fiber
mount options include 1,2,3,4,5,8,and 10° lenses. It can be used
with a sample contact probe, pistol grip, leaf clip, or benchtop
probe with sample compactor. The PSR+ stores up to 1,000
spectra without a computer and can be used with a laptop, tablet,
or the GETAC microcomputer with digital camera, voice note
recording, altimeter and more/ All scans and associated data are
stored as ASCII files for use with other third party programs, like
ENVI or chemometrics software.
Custom LIbrary Builder module, is also available for quickly and
Our optional EZ-ID sample identification software with the easily
creating a specific spectral library unique to your application.
PSR+ 3500 Spectroradiometer
DARWin SP Data Acquisition software provides access to 19
vegetation indices via built-in pull-down menus including NVDI, SR,
SAVI, ARVI, EVI, IPVI, PRI, SBI, PAR, and more. In addition, since
DARWin saves your spectra as ASCII files, they can be used with
a wide range of other software programs.
EZ-ID allows you to quickly and easily scan a known sample and build
a spectral library that is uniquely matched to your application and
includes your scan plus all associated metadata, such as operator,
time, date and location of sample - all critical information for remote
sensing applications as well as geological remote sensing.
