Chapter 1 Introduction
The spectral resolution is:
•
3 nm (Full-Width-Half-Maximum) at 700 nm.
•
10 nm (Full-Width-Half-Maximum) at 1400 nm.
•
10 nm (Full-Width-Half-Maximum) at 2100 nm.
The sampling interval is:
•
1.4 nm for the spectral region 350-1000 nm.
•
2 nm for the spectral region 1000-2500 nm.
The FieldSpec spectroradiometer may be configured to have three separate
holographic diffraction gratings with three separate detectors. Each detector is
also covered with the appropriate order separation filters to eliminate second
and higher order light.
•
VNIR: 512 element silicon photo-diode array for the spectral region
350-1000 nm.
•
SWIR1: graded index, TE-cooled, extended range, InGaAs, photo-diode
for the spectral region 1000 nm to 1830 nm.
•
SWIR2: graded index, TE-cooled, extended range, InGaAs, photo-diode
for the spectral region 1830 nm to 2500 nm.

Interface Requirement
The FieldSpec spectroradiometer has 10/100 Base T Ethernet port. The
spectroradiometer with an Ethernet cross-over cable can be directly connected
to the Ethernet port provided on many laptop computers.
The FieldSpec spectroradiometer can communicate with the instrument
controller using an 802.11b wireless card. When supplied by the customer, the
instrument controller must be 802.11b compatible.
The FieldSpec spectroradiometer uses industry standard components. It has
the same general connection speed and distance capabilities as other 802.11b
wireless devices.
For the best performance, ensure a clear line-of-sight between the
spectroradiometer and instrument controller. Obstructions or radio frequency
interference in close proximity can cause loss of communication or
significantly shorten the communication range.
Note:
For information about configuration of the Ethernet card and cable, please
refer to the
Installation Manual
