LIBS-6 & LIBS-8 Modules

Integrated modules for configuring a customised LIBS system
Compatible with a range of pulsed lasers and UV-Vis-NIR spectrometers
Essentially “LIBS system building blocks”, the LIBS-6 and LIBS-8 modules may be used together with a variety of Q -switched Nd:YAG lasers and optical spectrometers to form customised LIBS systems. This allows the user to assemble a LIBS system that best suits the requirements of their specific application or experimental research. The LIBS modules remove the need to design and construct your own laser focussing optics and plasma light collection optics by combining these features into a compact, integrated and easy to use device. An optional integrated video camera is also available.

Features
  • Allows easy conversion of a standard Q-switched Nd:YAG laser into a LIBS device (requires: adaptor platform to attach LIBS module to laser head, suitable spectrometer(s), fibre-optic cables and computer)
  • Available in 6-channel (LIBS-6) or 8-channel (LIBS-8) versions
  • High-efficiency plasma light collection optics – LIBS-6: 1 DUV, 2 UV-Vis, 3 Vis-NIR channels. LIBS-8: 1 DUV, 3 UV-Vis, 4 Vis-NIR channels
  • May be supplied with laser beam expander optics configured for all harmonic wavelengths of Nd:YAG lasers (contact us for available options)
  • Integral laser beam expander with adjustable focus (theoretical minimum spot size typically 30 - 100 microns depending on laser used)
  • Adjustable nozzle aperture – provides a convenient means of setting the distance to the sample
  • May be used in ‘open beam’ configuration (Class 4) or with fully-interlocked (Class 1) modular sample chambers
  • Fully compatible with our range of modular sample chambers
  • Working distances (nominal distance to sample): ~100 mm. Custom versions also available
  • Gas purge facility for supplying inert gas (argon, helium, nitrogen, air) to sample surface
  • Optional imaging camera kit (IMG-HR) for viewing sample surface. Kit includes high resolution colour camera, dimmable high-brightness white LEDs for illuminating sample and a USB video converter for connection to a PC
General specifications
Technology: Laser-Induced Breakdown Spectroscopy.
Laser source: Q-switched Nd:YAG (specify make, model and configuration of laser when ordering LIBS module).
Spectrometer: LIBS modules are compatible with various fibre-optic coupled spectrometers. Contact us for advice.
Plasma light collection: Six (or eight) collection lenses arranged in a circular array and covering wavelength range ~182 – 1016 nm.
Fibre-optic interface: Six (or eight) SMA 905 connectors located at rear of optics holder (see below). Use multiple single-core fibre-optic cables for multiple spectrometers or 6-into-1 (or 8-into-1) fibre optic bundle for single spectrometer. Contact us for advice.
Laser beam expander: Adjustable focus (approx. +/- 7 mm). Minimum spot size typically 30 - 100 microns depending on laser. Beam expander designed to suit specific Nd:YAG laser and operating wavelength.
Dimensions: Approx. 265 (L) x 122 (W) x 122 (H) mm, weight: ~2 kg.
Sample interface:  “Open beam” path to sample or via use of one of our modular sample chambers.
Optional sample chambers: Compatible with our range of modular sample chambers. See our website for further details.
Optional imaging camera: LIBS-6 and LIBS-8 modules are fully compatible with our IMG-HR imaging kit.
Optional software: Data acquisition, processing and recording via user-friendly LIBSoft™ software (please contact us for details on which lasers and spectrometers are supported by LIBSoft). NB LIBSoft is not necessary for operation of LIBS modules.
Product classification: Class 4 when used without modular sample chamber. Class 1 laser product when used with modular sample chambers and instructions given in User’s Manual are adhered to.
