The MPTflex is a CE- marked medical system based on femtosecond multiphoton excitation of biomolecules like NAD(P)H, flavins, porphyrins, elastin and melanin.
The extracellular matrix element collagen can be identified by its second harmonic generation (SHG). Autofluorescence and SHG signals are recorded by fast highly sensitive PMT detectors with single photon sensitivity.

The system consists of a compact, turn-key tunable femtosecond near infrared (NIR) laser, an articulated arm with near infrared optics, beam- scanning module with galvoscanners and piezo -driven optics, a fast PMT detector module as well as a control unit including JenLab Image software for 3D processing.
An additional module for two-photon in-vivo FLIM can be provided.
