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.

Industrial Solano systems (Solano housing temporarily unavailable, completely replaceable with the Quad design)
- Based on Solano enclosure design
- Noise/vibration isolation
- Advanced software
- Extended automation of standard tests
- Individually designed sample holders

Solano industrial systems features |
 |
Motorized XYZ scanning unit 1"x1"x1" or 2"x2"x2" (replaces manual version) |
Supplied with a range of individually designed sample holders for fast and convenient screening |
Programmatically controlled scanning unit. Automatic 2D/3D sample scanning. Automatic control of precise sample position |
Solano is equipped with "reflection unit" which is a complementary photodetector/s grabbing reflected probe laser beam making it possible to perform tests on HR coatings or coatings with non-transparant substrate |
