Home / Products / M-FIP

Flexible Probe for Multiphoton Multimodal Imaging

The M-FIP multiphoton endoscope enables multimodal nonlinear imaging such as 2-photon and 3-photon fluorescence but also harmonic generation (SHG, THG) and coherent Raman imaging (CARS).

The M-FIP probe is connected to a standalone cabinet that houses the laser, opto-electronics and computer. The M-FIP system is powered by a dedicated, user-friendly software.
