Key Advantages of DeltaFlex
1.
Extended Measurement Range
Enables precise analysis from ultra-fast events to long-lived photoluminescence.
2.
Expandable Modular Design
Easily integrate new sources, gratings, and detectors without complex reconfiguration.
3.
Comprehensive Wavelength Options
Supports multiple excitation sources and detectors for maximum versatility.
4.
Fast Data Acquisition
Captures rapid processes with exceptional accuracy and sensitivity.
Applications of DeltaFlex
PL-upconversion
Frequency upconversion from NIR to visible using lanthanide based nanomaterials. Lanthanide based nanomaterials exhibits a unique fluorescence anti-Stokes shift enabling conversion of NIR into visible shorter wavelengths.
Local viscosity determination
Certain fluorescent molecules known as molecular rotors, can be employed to estimate the nanoscale viscosity in micro heterogeneous systems by measurement of their fluorescence lifetime.
