The Hornet series of spectrometers have been developed based on LightMachinery's patented Fluid Jet Polishing technology. Designed for characterizing laser spectra, LightMachinery’s Hornet spectrometer is a compact, cost-effective spectrometer capable of better than 30 picometer resolution. This spectrometer is capable of attaining the resolution of large gratings spectrometers at a fraction of their cost and size while covering a huge wavelength range. The spectrometer’s simple PC based software allows the user to review spectra in real-time and export or save for further analysis. Labview drivers allow the Hornet spectrometer to be incorporated into automated experimental setups.

Drawing
How Does it Work?
Light enters the Hornet via a fiber. The beam is focused through a LightMachinery fluid jet polished etalon in order to produce extremely high dispersion in the vertical axis with sub 30 pm resolution. This is followed by a grating to cross disperse overlapping orders in the horizontal direction to develop a 2D spectrum of the input light, and the resulting pattern is then imaged onto the CCD detector. Finally, the spectrum is unwrapped by LightMachinery software to produce an ultra-high-resolution spectrum of the input light.
