FlexLambda Kit

In many areas of material science, including semiconductors, photovoltaics, and nanomaterials, characterizing photophysical properties requires selective access to specific emission wavelengths. Whether isolating spectral features, distinguishing recombination pathways, or comparing device performance, flexible and precise wavelength selection is essential. Traditionally, this is achieved using sets of discrete bandpass filters or monochromators, each with limitations in flexibility, speed, or photon efficiency.

The FlexLambda Kit provides a fast, flexible, and reliable solution for wavelength selection across the visible to near-infrared range. It enables users to quickly set spectral detection range as well as spectral bandwidth without exchanging any optical components, simplifying measurements across different samples.

Designed as a compact and fiber-coupled unit, FlexLambda can be integrated into a wide range of experimental setups, including microscopes for spatially resolved measurements, as well as spectroscopic systems, probe stations, cryostats, or custom optical configurations. It is particularly beneficial in experiments where efficient photon collection is critical, such as time-resolved measurements, by directing all selected photons onto a single detector.

FlexLambda is offered as part of a complete measurement solution. Customers who already own compatible PicoQuant components can integrate FlexLambda into their existing setup without repurchasing these items.

• SymPhoTime 64 software

Optional components:

• Compatible detectors, e.g. PicoQuant PMA Hybrid series
• Excelitas SPADs, or MPD PDM series detectors
• Multi-channel detection unit (LSM tower) for up to 4 detector
• Detection optics such as dichroic beamsplitters, short-, long-, or bandpass filters and neutral density filters
