StellarNet Spectrometer

Wavelength Opto-Electronic is the authorised dealer of Miniature StellarNet spectrometer.

StellarNet miniature spectrometers are portable & compact fiber optic instruments for UV, VIS, and NIR measurements in the 190-2300nm range. The StellarNet series of miniature spectrometers is a step up in low-cost instrument design, offering CCD 2048 & PDA 512/1024 detectors. The units are engineered to have no moving parts, no detector sockets, ruggedized aluminum enclosure, and an integrated A/D digitizer for unmatched durability and quality that outperforms any instrument in its class. Numerous models offer standard or high resolution (HR) optics for selected spectral ranges.
