GREEN-Wave Spectrometer Overview
The StellarNet GREEN-Wave miniature spectrometers are fiber optically coupled instruments with a wide selection of standard 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.
