Overview
Balancing high spectral resolution and low noise, it has higher spectral resolution and accuracy.
Product Details
FieldSpec 4（350-2500nm）
Higher and more portable
FieldSpec® yesASDThe star spectrometer product for the company's field remote sensing research has complete accessories and can be suitable for the vast majority of spectral measurement applications.
Most authoritative institutions in this field are almost usingFieldSpec® The product has published over ten thousand articles using it.
FieldSpec®4 yesFieldSpecThe new generation of products in the family combines high spectral resolution and low noise, while possessing higher spectral resolution and accuracy.
According to the different application needs of users, FieldSpec®There are four different models available：
FieldSpec 4 HR NG
Having in the shortwave near-infrared band6nmSpectral resolutionHigher resolution hyperspectral instruments can assist users in improving the accuracy of remote sensing classification applications and identifying more pixel information that could not previously be obtained from hyperspectral images.
FieldSpec 4 Hi-Res
Having in the infrared band8nmThe spectral resolution is more suitable for geological applications and other research fields that require the definition of narrow spectral characteristics, especially in the study of long wave radiation. For example, atmospheric science, geology, mineral analysis, etc.
FieldSpec 4 Std-Res
Having in the infrared band10nmThe spectral resolution is widely used, including remote sensing image interpretation, crop and soil research, radiance and irradiance calibration, etc.
advantage:
Completely designed for field remote sensing research
● With the sun as the light source, it has both higher spectral resolution and lower equivalent radiation noise
The fiber optic cable is strictly fixed to the host, calibrated as a whole, and traceable to the United StatesNIST
Beautiful appearance, sturdy and durable, ergonomic design, convenient user experience
Massive application literature, complete database, seamless compatibilityENVI、TSGWaiting for more third-party tool software
