Analytik, leading suppliers of innovative
analytical instrumentation to the UK and Ireland, is pleased to announce the
release of the FieldSpec 4 line of portable, full-range spectroradiometers from
ASD Inc., the global leader in portable high-performance analytical
instrumentation and materials analysis solutions. With this launch, ASD is
continuing its tradition of setting industry standards for ground truthing and
remote sensing measurement technologies.
The field collection of radiometric and reflectance spectra of intact materials
(often referred to as ground truth data collection) is essential for
interpreting unknown materials in multi-spectral and hyperspectral remote
sensing data, and validating sensor performance. Since sample removal for lab
study often destroys the sample's surface properties, and because lab study is
impractical for many large natural surfaces, researchers need a reliable field
device capable of providing laboratory-quality, field measurements with
illumination and viewing geometry equivalent to a satellite or aircraft sensor.
The FieldSpec 4 line has been designed for faster, more precise spectral data
collection. The powerful FieldSpec 4 line of full-range (350-2500 nm)
spectroradiometers provides researchers concerned with speed, the ability to
cover more ground faster while enjoying the same high data quality. Ultimately,
FieldSpec users can cover twice the area in a half of the time thanks to the
improvements in the SWIR 1 and 2 regions (1000-2500 nm). For applications
requiring the highest possible precision, the new spectrometer configuration
provides double the signal-to-noise performance. This results in much more
precise spectral data with no increase in measurement time. Researchers who are
looking at materials with features at the longer wavelengths will especially
benefit from these improvements.
The line consists of three models, the FieldSpec 4 Standard-Res, a general
purpose remote sensing spectroradiometer suitable for a wide range of
applications including hyperspectral image interpretation and validation. The
FieldSpec 4 Hi-Res is well-suited to geologic and other applications that
require definition of narrow spectral features, especially in the longer
wavelengths. The FieldSpec 4 Wide-Res model is perfect for multispectral and
other areas of research involving materials with broad spectral features such
as plant physiology.
"The main improvements to the FieldSpec 4 are the speed of spectrum
capture as well as the enhanced quality of the collected spectra," said
Dr. Brian Curtiss, CTO for ASD. "Performing reflectance measurements in
support of remote sensing studies requires waiting for the best solar
conditions, which often limits the time available to make quality measurements.
The FieldSpec 4 increases researchers' ability to move from site to site more
quickly, and make more measurements while also improving the quality of the
spectra captured in the field. ASD pioneered the use of portable spectroscopic
technology in remote sensing more than 20 years ago with the invention of the
first robust, high-performance, portable instrument that could be used in earth
science field work."
