SHG System

The TTS Second Harmonic Generation (SHG) spectroscopy/imaging test system uses a 1030 nm fiber femtosecond laser as the excitation source. Integrating an upright optical microscope module with a synchronized high‑speed scanning stage, it enables rapid SHG intensity imaging.

Products Feature

Polarization-dependent SHG intensity mapping (polar plots) 
The software rotates the half-wave plate to change polarization automatically and measures SHG intensity as a function of input laser polarization.
High-speed, high-resolution SHG intensity imaging (SHG mapping)
Using a synchronized high-speed stage, high-sensitivity detector, and high-speed acquisition card, the system achieves scanning speeds exceeding 700 points/s.
Measurement of SHG intensity versus excitation power
Software-controlled laser power adjustment enables fast acquisition of SHG spectra under different excitation powers.
Easy integration of confocal fluorescence, Raman, and other modules for fluorescence lifetime imaging, Raman spectroscopy/imaging, etc.
