The StellarNet GREEN-Wave low cost Spectrometers are fiber optic coupled instruments with a wide selection of models for measurements in 350-1150nm wavelength ranges. Each unit contains a USB-2 interface with a snap shot memory to provide instantaneous spectral image from the highly sensitive CCD for 2048 elements. Various models provide a choice of grating range and slit resolutions. A single strand fiber optic cable or probe assembly delivers input via standard SMA 905 fiber optic connector with a choice of cable lengths. The spectrograph optics are exceptionally robust in a vibration tolerant modular design, with no moving parts.
The detachable spectrograph assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable, process, and lab applications. Several units may be daisy-chained using a standard USB hub allowing simple configurations for dual and multi-beam applications in chemistry, spectroradiometry, and PORTA-LIBS.
View the Standard Models tab to choose between the various options for the GREEN-Wave spectrometers. If you are interested in UV or UVN (wide range) models you must upgrade to the BLUE-Wave series.

Additional Green-Wave measurement applications include emission wavelength monitoring /characterization of tunable lasers or LED’s and other sources such as elemental emissions from plasma & Laser Induced Breakdown Spectroscopy. Colorimetry and Optical Metrology are also common applications for this spectrometer. The small size and weight makes the GREEN-Wave low cost spectrometers just perfect for portable applications.

GREEN-Wave Sample Spectra
Free SpectraWiz Software
The powerful SpectraWiz® spectrometer software is provided free of charge with every spectrometer instrument. This includes drivers and customizable software for Windows. The SpectraWiz software is considered the “Swiss Army Knife of Spectroscopy” and may be used to accurately measure wavelength emissions, reflectance, transmission, absorption, concentrations, and absolute intensities. In addition to real-time spectroscopy, SpectraWiz® has built-in applications for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab concentration analyzer, and UV level monitors.
Units may be daisy chained via USB-2 hub allowing simple configurations for dual and multi-beam process applications. 8 BLUE-Wave spectrometers can be operated at once!
The system includes a high speed plug & play interface using USB-2 connection.
