IndiGo VIS Handheld Spectrometer: The Power of Spectroscopy at Your Fingertips

Indigo with Data

IndiGo VIS is a compact modular spectrometer that fits in the palm of your hand. This handheld spectrometer can be used for many different applications: it allows measurement of absorption, emission, or transmission spectra from 380 nm to 780 nm with a standard resolution of 1.5 nm (FWHM).

The IndiGo spectrometers are very versatile scientific tools that can easily be integrated into experimental setups to perform many types of measurements involving different types of light sources, cuvette and other sample holders, optical fibers, lenses, and many other elements.

Every IndiGo handheld spectrometer comes with a powerful PC desktop application, but it is also compatible with Android tablets and smartphones equipped with a Bluetooth 5.0 connection for increased mobility.
