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.

Measuring Spectral Irradiance- StellarNet

Green Wave low cost spectrometer- Ruggedized system for field applications (measuring solar emission)

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. for teaching lab and multi-unit volume discounts.

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.
