IndiGo VIS-NIR : The Ultimate Multi-Purpose Modular Spectrometer for Field and Laboratory

The IndiGo VIS-NIR is a modular visible and near-infrared spectrometer featuring a revolutionary compact design, engineered to fit right in the palm of your hand. It bridges laboratory-grade performance with absolute mobility. This allows you to perform high-precision diffuse reflectance, transmittance, and fluorescence analyses anywhere, anytime, from 400 nm to 1000 nm.

Full Connectivity and Field-Ready Battery Life

The IndiGo VIS-NIR offers dual USB-C and Bluetooth 5.0 connectivity to seamlessly integrate into your workflow (PC, tablet, or smartphone). Connected via Bluetooth, the device transforms into a fully mobile metrology tool thanks to its 8-hour continuous measurement battery life (and several days on standby). In wired mode, it utilizes the power of the USB-C port to operate while simultaneously recharging its battery.

Optical Performance and Fleet-Wide Reproducibility

This system accurately measures emission, absorption, reflection, and transmission spectra across an extended spectral band from 400 nm to 1000 nm, with an excellent optical resolution of under 1.5 nm (FWHM). The IndiGo VIS-NIR stands out for its exceptionally high level of instrument-to-instrument reproducibility. This unique consistency greatly simplifies the deployment and sharing of chemometrics and calibration models across entire fleets of devices deployed in the field.

Accessory Focus: Remote Measurements with the Fiber Optic Probe

To extend the capabilities of the IndiGo VIS-NIR to remote, non-contact, or micro-spot optical metrology, GoyaLab has engineered a high-performance multi-branch fiber optic probe. This dedicated accessory transforms your handheld spectrometer into an ultra-flexible testing station:

Mineralogy, Geology & Mining Exploration: Instant field or core logging identification of iron oxides (hematite, goethite), alteration clays, and critical Rare Earth Elements (REE) such as Neodymium Nd³⁺ or Praseodymium Pr³⁺ via their signature narrow absorption peaks.
Gemmology & Precious Stone Identification: Non-destructive, non-contact analysis of spectral signatures of gems (sapphires, rubies, diamonds), even when mounted on jewelry. It characterizes transition metal chromophores (Iron, Chromium) and tracks photoluminescence under 365 nm UVA excitation to accurately distinguish natural stones from synthetic ones (CVD/HPHT).

A Modular Spectrometer Tailored to Your Industrial Applications

In addition to the remote fiber optic probe, the IndiGo VIS-NIR features a full range of interchangeable, “plug-and-play” optical modules:

### Leaf-Clip Spectrometer Module (Reflection & Transmission) Specifically engineered for characterizing living plant tissues or diffusing polymer films.

Application Examples: Early diagnostics of abiotic stress (drought, thermal) in crops by monitoring the critical water absorption band at **970 nm** and automatically calculating physiological indices (NDVI, PRI). It can also track the photo-conversion and aging of agricultural greenhouse plastics to optimize the photosynthetic active radiation (PAR) needed to accelerate crop growth.

### Broadband Reflection & Optical Sorting Module Ideal for direct surface analysis via diffuse reflectance on solid samples or powders.

Application Examples: Assessing the maturity and sugar content of fruits and vegetables (correlating pigments/water content), monitoring meat freshness, or real-time automated sorting of polymers (PET, PE, PP) and textiles in recycling centers.

### Cuvette Transmission Module Designed for rapid quantitative and qualitative characterization of liquid products and translucent chemical solutions.

Application Examples: Kinetic tracking and solute quantitative assays (Beer-Lambert law), turbidity monitoring, fermentation process control (optical density at OD600), and profiling of vegetable oils or biofuels.

### Forensic Sciences (Standalone or via Fiber Probe) Direct analysis of fluids, emissions, or luminescent security taggants.

Application Examples: Non-destructive detection and bloodstain dating at crime scenes by tracking hemoglobin oxidation kinetics ($HbO_2 \rightarrow met-Hb$), body fluid screening via unique fluorescence signatures under 365 nm UVA excitation, and anti-counterfeiting verification of secure documents or banknotes.

A Complete Software Ecosystem: From Capture to Chemometrics

The IndiGo VIS-NIR is supported by a powerful software suite designed to exploit and instantly analyze your spectral data:

SpectroLab (Windows): Comprehensive laboratory software included as standard to capture spectra, control individual source toggles (hyperspectral LED or 365 nm UVA), apply essential mathematical processing (absorbance, transmittance, white reference blanking), and save your datasets.
Android Application: Available on the PlayStore, it allows operators to drive the spectrometer via smartphone or tablet over Bluetooth for ultra-mobile, geolocalized field measurements.
« SpectroLink » Python Library: Allows developers to control the IndiGo VIS-NIR directly from any Python IDE. Perfect for automating industrial test benches or integrating your own multivariate chemometric classification models (PCA, PLS).

📦 Shipping & Packing Information: Every IndiGo VIS-NIR unit is shipped pre-calibrated in wavelength (nanometric scale). The multi-branch fiber optic probe and optional modules can be bundled and ordered concurrently.
