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).

CARS/SHG – Humain Colon Lipid(Red) and Collagen(Green)
CARS – Human Colon Lipid
Mouse spinal cord: Myelin (magenta – CARS), spinal axon (blue – 2photon)
Human skin: stratum corneum (autofluorescence)
Mouse brain labelled with GCamp (2photon)
Collagen fibers: rat tail tendon – SHG

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.

The M-FIP multiphoton endoscope can also use your favorite table-top multiphoton laser using the Lightcore multiphoton delivery fiber (M-DF)
