EPP2000-GREEN-Wave
Range 190-1150nm
The StellarNet GREEN-Wave Spectrometers are fiber optic coupled instruments with a wide selection of models for  measurements in 190-1150nm wavelength ranges. Each unit contains a USB interface with a snap shot memory to provide instantaneous spectral image from the highly sensitive CCD or Photo Diode Array detectors with options for 2048 or 3648 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.


Green Wave-  
Ruggedized system for field applications (measuring solar emmision)



         

GREEN-Wave small size just 1x3x5 inches!! Compare the size with the EPP2000C


Interface
The system includes a high speed plug & play interface using USB-1 connection.
 

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.

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. Also Bragg grating technology enables optical sensing of many parameters including temperature and pressure. Thin film thickness measurements can be made using sample specular reflectance. The small size and weight makes the GREEN-Wave spectrometers just perfect for portable and OEM applications. CCD has best sensitivity and PDA has best SNR.

Optional Configurations
Several units may be daisy chained via a parallel cable or USB-2 hub allowing simple configurations for dual and multi-beam process applications.  

Free SpectraWiz Software
The powerful SpectraWiz® 32 bit spectrometer software is provided free of charge with every spectrometer instrument.  This includes drivers and customizable software for operation on Win95 / Win98 / WinNT / WinME / Win2000 /WinXP.    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.
