Photothermal systems

Based on Photothermal Common-Path Interferometer (PCI) concept

The instrument
  • Detects the thermal effect of absorption.
  • Insensitive to scattering.
  • Has moderate 3D resolution:
    • test substrate behind the coating, interface between bonded parts
    • make 2D or 3D maps of absorption patterns
  • Can be used to monitor induced, time-dependent absorption:
    • gray tracks,
    • laser-induced transparency (bleaching),
    • initial stages of optical damage, etc.

Custom made systems
If you have any special requirements for materials characterization or you'd like to integrate PCI in your quality control system or you are just looking for a bit different resolution, spectral range, scanning speed or any other parameter which our standard Solano and Quad instruments do not meet we'll be glad to consider your inquiry!
