• How Does it Work?

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.
