Technology Overview

The three-photon (3P) microscopy allows noninvasive functional imaging of the deeper tissues with higher axial resolution compared to the two-photon excitation. 3P excitation is performed at longer excitation wavelengths which are scattered less in the biological tissues This allows extending the penetration depth, reduces out-of-focus excitation, and increases the SNR.


  • excitation wavelength range:1,200-1,600 nm

  • XY resolution bigger than 500 nm, Z resolution ~ 1 µm

  • excites fluorophores in the wavelength range from blue to green

  • no noticeable tissue damage


  • Second and Third Harmonic Generation

  • functional imaging through the whole cortical depth
