Item Code: USB4000-FL

The USB4000-FL is a miniature spectrometer pre-configured for fluorescence measurements from 360-1000 nm. The spectrometer can be used with linear variable filters to construct systems with excellent separation of excitation and fluorescence energy.

  • Modular – covers the 360-1000 nm range and connects to light sources, cuvettes and other accessories
  • Fast – integration time is 3.8 ms – 10 seconds
  • Portable – fiber optics based spectrometer you can bring to the sample
  • Compatible – triggering functions synchronize the spectrometer to other devices
