Product information "HF-8999-xxx-AUTO Brillouin HyperFine Spectrometers"

VIS; 531-782 nm; Resolution 1, 1.5 pm; Dynamic Range (@6 kHz From Pump) 100 dB; Interface USB 3.1; 711x371x124 mm

The great challenge with Brillouin spectroscopy is that the scattered signal from the un-shifted wavelength of the laser can overwhelm the small Brillouin shifted return signal. So, for the HF-8999-xxx-AUTO Brillouin HyperFine series of spectrometers, Light Machinery has combined their leading-edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shifted laser frequency.

The Brillouin HyperFine series’ tunable filter is easily adjusted to suppress the main laser peak, and exposure gating is used to drastically increase the full dynamic range of the instrument. The combination of these two devices achieves a dynamic ratio of 65 dB with Light Machinery’s standard CMOS camera and is designated – the “Green Killer” (for the 532 nm model HF-8999-532-AUTO). The tunable filter is comprised of a double passed air spaced etalon. The etalon tuning and alignment are both computer-controlled.

LightMachinery’s proprietary fluid jet polishing process is utilized to create both the tunable etalon filter and the main VIPA etalon in the Brillouin HyperFine spectrometer. The result of the combination of the high-finesse elements is unparalleled sensitivity and relatively compact size, perfect for Brillouin scattering.

Designed for measuring hyperfine spectra and subtle spectral shifts, the Brillouin HyperFine series are compact spectrometers capable of 1 pm resolution. Light enters the 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.

Simple PC-based LightMachinery software unwraps the spectrum to produce an ultra-high resolution wavelength spectrum of the input light and allows the user to review spectra in real time and save or export measured data for further analysis. LabView drivers enable the HyperFine spectrometers to be integrated into automated experimental setups. A secondary camera provides a wide wavelength range, lower resolution view of the spectrum.
