Key Benefits

Take the experiences and requirements of the users, who work with the elemental analysis on the daily basis. Mix in the unique benefits of LIBS technology and you get the FireFly.

Clear Sample View

No more blurry images! Laser ablation optics are combined with dedicated microscopy sample view optics to provide you with clear and sharp images of a sample being analyzed.

Illumination is of a dual-type to adapt to the wide spectra or sample types:

  • Colinear LED Illumination
  • Diffused LED illumination
Precise sample image

Quick targeting

You will never get lost on magnified sample surface while searching for desired spot for the analysis.

  • Switch between multiple Field of Views.
  • Create whole-stage overview image
  • Move the sample simply by mouse button click on desired spot.

Measurement modes

Whether you want to check few spots dispersed on the sample or perform large area scan, FireFly has a right tool.


Multispot mode

Schedule a series of spots and start the measurements at once.


Mapping mode

Scan the are to visualise concentrations of multiple elements.

Line scan

Linescan mode

Scan along the line, boundary or vein by drawing a polygonial line.

Depth profiling

Depth profiling

For each spot, a total number of laser pulses and measurements can be set. Resulting group of spectra from each spot can be used for:

  • Accumulation for improving the signal to noise ratio thus improving the limits of detection.
  • Multi-layer depth analysis to determine elemental composition of individual depth layers of the material.

Spectra and Maps

Explore the results in a form of spectra and chemical maps utilizing flexible and intuitive tools.

  • Pan, Scroll, Scale, and change color histogram.
  • Use Max, Mean, SDEV, and Peak overlay curves to simplify the quick spectra evaluation.
  • Quickly re-draw the map to display the distribution of concentration of a different element.
  • Filter spectra by unique metadata.
  • Show atomic emission lines from NIST and/or Lightigo LIBS database
  • Export to ASCI, Bitmap, or Lightigo optimized data file.

    Technical Highlights

    Laser Wavelength


    With the FireFly you can always select laser wavelength, which is optimal for your current applications.

    • Do you need a smaller spot size or high absorption for transparent materials? Select UV 266 nm.
    • High pulse energy is the priority?
      Switch to IR 1064 nm.
    • Or simply utilize versatile VIS 532 nm.

    There is no need to disassemble or adjust anything. Switching is motorized and can be controlled directly from the control software.

    Laser Wavelengths

    Multiple objectives

    Different optical tasks require different objectives in order to be solved without any compromises:

    • Multiple plan-apochromatic objectives for sharp sample view with various magnifications.
    • High damage-threshold objectives corrected for precise laser focus either in micro-focus or long-depth of focus versions.

    FireFly has them all  – moreover, mounted on motorized objective turret controlled via single button click in SW!

    Laser focusing

    FireFly can handle non-flat samples, which otherwise might cause laser defocus and signal fluctuations during the mapping.

    • Autofocus, even during the mapping.
    • Dedicated long depth of focus (DOF) objective.
    Laser focus
    Laser spot size

    Motorized focusing stage can be used to change the laser spotsize on the sample directly from the control software.

    • Less than 20 µm spot size can be achieved by aperture imaging technique.

    Gas modules

    Gas purge

    • Cleans the sample to avoid „smearing“ of the signal to surrounding spots on the chemical map.
    • Creates local inert gas atmosphere to significantly improve the limits of detection.

    Dust Extraction

    • Extracts potentially toxic vapors of laser ablation
    • Keeps the optomechanical components clean.

    Core Components

    Lasers, spectrometers, and detectors are the core components of every LIBS system.

    There are multiple configurations of which we always select the optimal one based on customers’ requirements.


    DPSS Nd:YAG pulsed laser is used for inducing the plasma.

    • Modern and efficient Diode-Pumping (DPSS).
    • Longer life-time, and better stability compared to the traditional FPSS lasers.
    • Effeciency of the DPSS results in a lower power consumption, quite run, and simple air cooling.
    • 24/7 operation capability.
    • Motorized pulse regulation, energy meter and wavelength conversion is available.


    Plasma radiation is captured by the UV-NIR collecting optics and spectrally decomposed by the spectrometer.

    • Compact multichannel Czerny-Turner spectrometers.
    • High-performance Echelle spectrometers.


    Radiation is captured by the detector and converted into the spectra.

    • Basic CMOS detectors.
    • Advanced sCMOS or EMCCD detectors.
    • Specialized intensified sCMOS/CCD detectors

    Every obstacle counts
             when analyzing for hours …

    We are aware of this, so we have put our effort to design an efficient and comfortable work position with easy chamber/sample access.

    • A spacious front window enables one to observe the interaction area and laser ablation from the front.
    • Side windows enable the user to see into the chamber while sitting in front of PC.
    • The Chamber door handle is perfectly accessible directly from the PC. Just extend your arm and open the wide chamber door to comfortably handle the sample.
