Overview of FLIMsight PRO
The FLIMsight PRO is an all-in-one benchtop solution that seamlessly integrates 2-photon excitation, fluorescence lifetime imaging, and phasor plot analysis for real-time, label-free diagnostics. Its compact design and user-friendly workflow simplify advanced imaging for researchers and clinicians alike. Optimized for detecting key metabolic coenzymes such as NADH and FAD, the FLIM system features dual-channel fluorescence lifetime acquisition, enabling precise differentiation of metabolic states in biological tissues. The system’s integrated two-photon laser, operating at 780 nm with a 40 MHz repetition rate, ensures deep tissue penetration while maintaining high spatial resolution. Detection is achieved through fast photomultiplier tubes (PMTs) with a 150 ps instrument response function (IRF), allowing for highly sensitive and accurate lifetime measurements. Utilizing FastFLIM technology, the system captures lifetime decay dynamics with exceptional speed, while advanced analysis tools, including multi-exponential fitting and phasor plot analysis, enable intuitive and quantitative data interpretation. With its streamlined workflow, compact design, and fully integrated hardware and software, the FLIMsight PRO simplifies advanced fluorescence imaging, making cutting-edge FLIM applications more accessible to both biomedical researchers and clinical professionals.

3D Volume Rendering

An example of 3D volume rendering with FLIMsight PRO. A stack of z-sectioning images acquired from a pollen grain, using the two-photon laser excitation at the 780 nm wavelength.
Hematoxylin and Eosin-stained Tissue

Image acquired from a hematoxylin and eosin-stained tissue using the two-photon laser excitation at the 780 nm wavelength and a hybrid PMT photon counting detector. Both are capable of fluorescence lifetime imaging (FLIM). Together with ISS FastFLIM technology, it is straightforward to collect the fluorescent decay data at each image pixel. The time-resolved data is quantitatively unmixed by the ISS VistaVision phasor plots module producing three separate images which represent the fluorescence intensity contributed exclusively by distinct fluorescent species. The merged image is constructed utilizing false red, green and blue colors for shortest, intermediate and longest lifetime species, respectively.
Two-Component Lifetime Unmixing using the Phasor Plot
Using the phasor plots of the FLIM images acquired from NADH in live cells and solution which only contains the free form, multi-image phasor analysis (MiPA) derives the phasor coordinate of the bound form of the cellular NADH. MiPA computes the fractions of both free and bound NADH for each pixel in the cellular NADH image, producing a cellular map depicting the ratios of free-to-bound NADH. Given the free and bound NADH lifetimes, it also generates the cellular NADH average lifetime map.
