Product Description

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.

  • Measurements in the 350-1150nm wavelength range
  • Most Affordable model with volume discounts available
  • 8 standard models with options for customized wavelength ranges
  • Signal: noise = 400:1
  • 1x3x5″ compact enclosure allows for eXtreme portability
  • New! low power consumption for 2x longer lifetime on tablets/laptops
  • Great for teaching and educational labs!

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.
