One-picometer resolution and unique capabilities of LightMachinery’s HyperFine spectrometers open possibilities for exploring unchartered waters in many fields. It’s not surprising, then, that LightMachinery often collaborates with potential customers and researchers to test novel measurements and samples or to fine-tune spectrometer design to meet customers’ needs.
Dr Cédric Chaminade, Technical Director of Raymax which distributes LightMachinery in Australasia, says its off-the-shelf spectrometers achieve the highest resolution in the pm range.
“And LightMachinery also customises systems for a specific spectral range or application – such as plasma characterisation requiring a large input aperture and very high transmission,” says Cédric.
Enabled by VIPA etalons produced by LightMachinery’s patented fluid jet polishing technology, its HyperFine HF Series spectrometers are also ideal for measuring fine features in pulsed laser characterisation and for measuring the small spectral shifts from Brillouin or Raman scattering.
In a collaboration with North Coast Photonics (formerly MSTATT LLC) which helped show the potential of Brillouin spectroscopy for early detection of dental cavities, the HF-8999-532-AUTO system was used to measure the Brillouin signal of bovine enamel (similar to human enamel).
The same system, this time in collaboration with France’s Alternative Energies and Atomic Energy Commission, demonstrated the suitability of VIPA-based Brillouin spectroscopy for diamond anvil cell measurements.
One of LightMachinery’s ongoing collaborations, this time with Nikon, is to develop a coupling module for HyperFine systems.

Simple PC-based software allows users to review spectra in real time as well as capture for later analysis and LabView drivers help integrate the spectrometer into automated, experimental setups.
The company has ongoing collaborations on many other Brillouin projects as well as Raman spectroscopy, optical coherence tomography and laser-induced breakdown spectroscopy projects.
LightMachinery is a pioneer in optical design, high-powered lasers, optical fabrication, laser systems, remote sensing, metrology, thin film coatings and custom machinery fabrication. The Ottowa-based company has produced components and equipment used in space science, telecommunications, for semiconductors, non-destructive testing, biophotonics, electronics, pharmaceutical manufacturing and materials processing.
