Compact, picometer resolution spectrometers for weak or scattered light

The HyperFine series of spectrometers for low intensity sources are designed for measuring hyperfine spectra and subtle spectral shifts from scattered light or distributed sources.  The HyperFine spectrometer from LightMachinery is a compact  spectrometer capable of 1 picometer resolution.   Enabled by VIPA etalons produced by LightMachinery's patented fluid jet polishing technology.  

The HyperFine HF Series spectrometers are ideal for measuring fine features in plasmas, pulsed laser characterization and for measuring the small spectral shifts from Brillouin or Raman scattering.  Simple PC based software allows the user to review spectra in real time and save or export for more analysis.  LabView drivers enable the HyperFine spectrometer to be integrated into automated experimental setups.

    Inside the HyperFine spectrometer.jpg

    Light enters the HyperFine Spectrometer though a fiber.   A VIPA etalon, manufactured using LightMachinery's proprietary fluid jet polishing technology,  is used to produce very high dispersion in the vertical axis with sub picometer resolution.  This is followed by a conventional grating to disperse overlapping orders in the horizontal direction and produce a 2D spectrum of the input light.  LightMachinery software unwraps the spectrum to produce an ultra high resolution wavelength spectrum of the input light.  A secondary camera provides a wide wavelength range, lower resolution view of the spectrum.
