The USB4000 is an economical, versatile spectrometer supporting thousands of applications. Its 3648-element CCD array detector and powerful high-speed electronics provide an high spectral response and optical resolution in a single package. The result is a compact, flexible system, with no moving parts, that’s easily integrated as an OEM component

Modular – covers the 200-1100 nm range and connects to light sources, cuvettes and other accessories

  • Convenient – ideal for embedding into OEM devices
  • Portable – fiber optic-based spectrometer you can bring to the sample
  • Compatible – triggering functions synchronize the spectrometer to other devices
