IndiGo UV/Vis: Handheld, Connected, and Affordable Visible Spectrometer

The IndiGo UV/Vis is a revolutionary, pocket-sized modular visible spectrometer designed to fit in the palm of your hand. Combining laboratory-grade performance with ultimate mobility, it enables high-precision spectral analysis anywhere, at any time, across the 380 nm to 780 nm wavelength range.

Full Connectivity and Field-Ready Battery Life

The IndiGo UV/Vis features dual USB-C and Bluetooth 5.0 connectivity, seamlessly integrating into your workflow across PCs, tablets, or smartphones. When connected via Bluetooth, it becomes a fully autonomous portable metrology tool, delivering 8 hours of continuous measurement battery life (and several days on standby). In wired mode, it utilizes power directly from the USB-C port to operate while recharging its internal battery.

Optical Performance and Fleet Calibration Management

This compact system measures emission, absorption, and transmission spectra with an excellent optical resolution of under 1.5 nm (FWHM). A key advantage of the IndiGo UV/Vis is its exceptionally high level of inter-device reproducibility. This unique consistency makes it easy to deploy and share complex calibration models across entire fleets of devices deployed in the field.

Featured Accessory: Optical & Astronomical Filter Characterization with GoLight

To extend the capabilities of the IndiGo UV/Vis into precision optical metrology, GoyaLab engineered the GoLight. This dedicated illumination accessory transforms your handheld spectrometer into an ultra-compact optical testbench for measuring the transmittance of optical components.

• Astronomical Filter Testing: Instantly map the transmission profiles of your narrow-band or multi-band astrophotography filters (OIII, H-alpha, SII, as well as light pollution reduction filters like CLS/UHC). Easily check peak transmission, exact center wavelength (CWL), and Full Width at Half Maximum (FWHM).
• Industrial Optical Filter Quality Control: Perfect for rapid, non-destructive testing of passband, longpass, or shortpass filters, verifying coated or tinted optical glass compliance before final assembly.

A Modular Spectrometer Built for Diverse Industrial Applications

Alongside the GoLight, the IndiGo UV/Vis can be customized using our versatile range of “plug-and-play” interchangeable optical modules:

• Reflection & Colorimetry Module: Engineered for surface color analysis on solid samples, textiles, or powders.
  Key Applications: Rigorous color metrics and quality control within the CIE L*a*b* color space (paints, plastics, inks, packaging), or verifying fluorescent security markers for brand protection.
• Cuvette Transmission Module: Optimized for rapid chemical characterization of liquids and translucent liquid solutions.
  Key Applications: Quantitative solute dosing using the Beer-Lambert law, water quality analysis (monitoring organic pollutants or dyes), turbidity checking, and tracking natural pigments (like chlorophyll or carotenoids) in vegetable oils or beverages.
• Emission Spectroscopy (No additional module required): Direct analysis of active light sources.
  Key Applications: Spectral characterization and quality control of light sources (LEDs, displays, lasers) and fluorescence measurements under UV/Vis excitation.

Comprehensive Software Ecosystem: From Spectral Capture to Color Metrics

The IndiGo UV/Vis is supported by a powerful software suite designed to let you process and analyze your visible spectra instantly:

• SpectroLab (Windows): Our comprehensive standard software included with the device, built for spectral capture, essential mathematical processing (absorbance, transmittance, colorimetric coordinates), and data exporting.
• Android Application: Available on the PlayStore, it allows operators to drive the spectrometer via a smartphone or tablet for ultra-mobile field testing.
• « SpectroLink » Python Library: Control the IndiGo UV/Vis directly from any Python IDE. This tool is ideal for developers looking to automate filter verification sequences with the GoLight or implement custom quantitative analysis algorithms on raw data.

📦 Delivery & Options: Every IndiGo UV/Vis is shipped pre-calibrated in wavelength (nanometric scale). The GoLight and optional testing modules can be bundled with your initial order. Absolute intensity (radiometric) calibration is available as an option for emission metrology.
