Every MicroPL is equipped with a computer-controlled XYZ stage includes the FluoracleMap software package. This software add-on allows acquiring 2D, 3D and surface maps of photoluminescence lifetimes, as well as complex data analysis such as multiexponential decay fitting and a wide range of map display options.
Widefield excitation uses a liquid light guide coupling to the spectrometer to excite the full field of view of the objective.
Point excitation can be performed with either CW or pulsed lasers for spectral or lifetime PL measurements. MicroPL is compatible with Edinburgh Instruments EPL, HPL, and VPL diode lasers. A spot size of ~2 μm (source and objective dependent) is achievable, enabling to resolve PL spectra and lifetimes in the micrometer scale.​
Both Time-Correlated Single Photon Counting (TCSPC) and Multi-Channel Scaling (MCS) operating modes are compatible, covering a wide range of photoluminescence lifetimes, from a few ps up to seconds. Non-standard applications such as upconversion PL microscopy are possible with the appropriate choice of filters and laser coupling.
MicroPL can be configured with a computer-controlled XYZ stage for Fluorescence Lifetime Imaging Microscopy (FLIM). The FLIM add-on unlocks special features in the Fluoracle software (FluoracleMap) including control of the stage and advanced analysis options for maps, such as multi-component decay fitting algorithms. No additional software packages are required to obtain and analyse data.​
