FLIM system LIFA

LIFA is a complete system for the measurement of time-resolved fluorescence or FLIM (Fluorescence Lifetime-Imaging Microscopy). It can be very easily connected to all common fluorescence microscopes and allows extremely fast image acquisition, both in terms of measurement time in a few seconds, as well as the recorded processes from 0 – 300 ns with an accuracy of 30 ps.
Lambert Instruments’ Gen II and Gen III amplifiers are built into the setup to provide the highest resolution and sensitivity, even at low fluorescence in the spectral range from UV to NIR.
The whole system consists of a modulatable and amplified CCD camera, a modulated light source (LED or laser), a control unit for the modulation and a computer with LI-FLIM software. The camera used is either a HiCAM from Lambert Instruments, or the Toggel camera specially designed for LIFA.
LIFA can be used with a custom PC setup (see Specifications table for PC requirements). For more challenging applications, Lambert Instruments offers the STAMINA setup, which combines control (PC, software) with amplifiers and cameras.
The LIFA-TD system is a more affordable and simpler version compared to the LIFA, there the TRiCAM from Lambert Instruments is integrated. The entire system consists of TRiCAM and pulsed light source, which are connected to a fluorescence microscope. This allows TD-FLIM (Time Domain Fluorescence Lifetime-Imaging Microscopy) to be measured with one setup as a “turn-key solution”, the software automatically synchronizes the light source and camera, and lifetime results can also be calculated directly from the images with the software.
