The Hornet Spectrometer from LightMachinery - compact, < 30pm resolution in the Vis and NIR

The Hornet series of spectrometers are based on LightMachinery's patented Fluid Jet Polishing technology.  Designed for characterizing laser spectra, the Hornet spectrometer from LightMachinery is capable of better than 30 picometer resolution.   The Hornet Spectrometer achieves the resolution of large gratings spectrometers while covering a larger wavelength range.  Simple PC based software allows the user to review spectra in real time and save or export for more analysis.  Labview drivers enable the Hornet spectrometer to be integrated into automated experimental setups.

    Light enters the Hornet through a fiber.  The beam is focused through a LightMachinery fluid jet polished etalon to produce very high dispersion in the vertical axis with sub 30pm resolution.  This is followed by a grating to cross disperse overlapping orders in the horizontal direction to produce a 2D spectrum of the input light , the resulting pattern is imaged onto the CCD detector, LightMachinery software unwraps the spectrum to produce an ultra high resolution spectrum of the input light.
