The StellarNet GREEN-Wave miniature spectrometers are fiber optically coupled instruments with a wide selection of models for measurements in 350 -1150nm wavelength ranges.

Various models provide a choice of grating range and slit resolutions. New and improved electronics with a high speed 16-bit digitizer allows for fast data acquisition and a signal to noise of 400:1!

Ruggedized – The detachable spectrograph assembly and control electronics are protected inside a rugged metal enclosure, suitable for undergraduate use:-)

Multi-unit connection (up to 8) can be daisy chained together and are able to run simultaneously.

USB Powered – GREEN-Wave miniature spectrometers can be powered directly from your PC USB-2 port. 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.

Onboard Memory with pre-set calibrations and spectrometer settings and snap shot memory to provide instantaneous spectral image from the highly sensitive CCD with 2048 data points.

GREEN-Wave Options

Optional Configurations
Units may be daisy chained via USB-2 hub allowing simple configurations for dual and multi-beam process applications. 8 GREEN-Wave spectrometers can be operated at once!

Jack-in Trigger upgrade NOT available for the GREEN-Wave. BLUE-Wave series electronics or newer is required.


GREEN-Wave Interfaces

Interface
The system includes a high speed plug & play interface using USB-2 connection.


Systems / Applications

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.
