FS5 Spectrofluorometer

 

Modular design – enables flexibility, customisation for measurement needs and ease of future upgrades
Unrivalled spectral coverage from the deep UV to the mid‐IR range up to 5500 nm – allows the widest possible range of samples to be measured
Highest Sensitivity (>25,000:1) – Industry leading sensitivity, allows detection of very weak fluorescence signals
High performance triple grating monochromators with integrated filter wheels – high stray-light rejection allows more accurate results for highly scattering or weakly emitting samples

 

The FS5 is designed to meet the highest measurement specifications in the research and analytical markets. To achieve optimal sensitivity, resolution, and acquisition speed, we select only the optimal performance photomultipliers in temperature stabilised housings, and utilise an optical design that includes plane, spherical, toroidal, ellipsoidal mirrors and optimised mirror coatings; the FS5 is truly unrivalled in its spectral performance and sensitivity.


Not only does this superior design guarantee the highest sensitivity and broadest wavelength coverage, but it has also been optimised for a small bright focus at the sample position. This is important for measuring small sample volumes and benefits many sample holder attachments like a plate reader, fibre launch optics mounting, titrators and sample positioners.


The standard FS5 has a number of upgrade routes that are unique in its class, including spectral range extension up to 1650 nm, Fluorescence and Phosphorescence Lifetime measurement capabilities, polarisation / anisotropy and much more. Please see the upgrades tab for more information.
