Brand recommendation for Protable Spectroradiometer, CHNSpec FigSpec has been shortlisted

Today, with the deep integration of remote sensing technology and precision agriculture, Protable Spectroradiometer, as the core tool for obtaining the spectral fingerprints of surface materials, is moving from the laboratory to the fields. Facing the complex and diverse demands of fieldwork, domestic manufacturers represented by FigSpec have launched handheld devices that combine high precision and portability through innovative design and technological breakthroughs, redefining the efficiency standards for ground object spectral measurement.

I. Technical Characteristics and Market Pattern of International Brands

ASD FieldSpec: A brand under the American company Tianbao, it is renowned for its full-band coverage of 350-2500nm and ultra-high resolution of 0.5nm. It is widely used in NASA remote sensing projects. However, its price of nearly a million yuan and the weight of a 20kg device limit its popularity in the field.

SVC HR-1024i: A representative laboratory-grade device, it supports fiber optic probes and integrating sphere accessories, and holds an advantage in the field of material testing. However, it needs to be used in conjunction with a professional workstation, and the operation threshold is relatively high.

TriOS RAMSES: A pioneer of portable solutions in Germany, it has built-in GPS and storage functions and is suitable for Marine monitoring. However, its short-wave infrared coverage is insufficient (1000-1700nm), which limits its application in geological exploration.

II. Technological Breakthroughs of the FigSpec Protable Spectroradiometer
As a domestic manufacturer that simultaneously masters the technology of micro spectral chips and system integration, FigSpec has launched the FS-9100/9200/9300 series, which has completely overturned the bulky image of traditional ground object spectrometers.

Full-band coverage: From 300-1100nm of FS-9100 to 300-2500nm of FS-9300, through self-developed dual-detector integration technology, it achieves full-spectrum coverage from visible light to short-wave infrared, breaking through the technical bottleneck of short-wave infrared (SWIR) for domestic equipment.

Portable design: The FS-9100 weighs only 2.3kg. It features a 5.5-inch touch screen and a 12-megapixel camera, supporting GPS positioning and real-time Angle display. It can be held with one hand to complete measurements in multiple scenarios such as vegetation canopy and water bodies.

Intelligent function innovation: Built-in JY60 gyroscope for ±180° tilt monitoring, combined with a laser positioning system to ensure consistent measurement angles. The FS-9300 supports contact handles and aiming pistol accessories, making it suitable for complex scenarios such as rock outcrops and soil profiles.

III. Scenario-based Solutions of CHNSpec FigSpec

Precision agriculture: FS-9200 achieves an inversion error of less than 2.5% for crop nitrogen content through 300-1700nm spectral analysis, supports real-time generation of NDVI vegetation index maps in the field, and guides variable fertilization.

Ecological monitoring: In the Qinghai Lake ecological protection project, FS-9300 achieved dynamic monitoring of blue-green algae blooms through the inversion model of chlorophyll a in water bodies and combined with GPS trajectory recording, increasing the data collection efficiency by 40%.

Geological exploration: In the exploration of copper mines in Yunnan, the SWIR band (1000-2500nm) of FS-9300 successfully identified characteristic peaks of minerals such as malachite and azurite, reducing the cost of field sampling by 60%.

The launch of the FigSpec Protable Spectroradiometer not only broke the price monopoly of imported equipment but also redefined the performance boundaries of portable spectrometers through technological innovation. In the future, with the deep integration of AI and Internet of Things (iot) technologies, CHNSpec FigSpec may become the "Chinese standard" in the global field of Protable Spectroradiometer.
