Field Pro Spectrometer

"High-precision + Portable + Full-scene" professional-grade ground object spectral detection

High-precision optical performance
Full-scene portable adaptation
The software and hardware are deeply coordinated
High customization and expandability

Overview

Introduction:

The Field Pro Spectrometers are a wide-spectrum on-site detection system independently developed by Venuslab. Their core positioning is a "portable, high-precision ground object spectral measurement tool", specially designed for on-site detection in fields such as soil, minerals, crops, water quality, and forestry ecology.

They can replace traditional "bulky, large, and clumsy" laboratory spectrometers, enabling rapid sampling inspections in scenarios such as the wild and construction sites, without the need for sample preparation and submission procedures. Currently, the series includes three models: VL-Field1100, VL-Field1700, and VL-Field2500, covering different spectral measurement needs.

Features:

High resolution and sensitivity
Stable optical transmission
Strong outdoor endurance and protection
No sample preparation required
Data closed-loop processing
Low-threshold operation
Customization of wavelength range
Flexible expansion of accessories
