EagleEyeTM Series

  • Back-illuminated type sensor, cooling 25 degrees
  • High signal ratio, high sensitivity, ultra high resolution, low heat and dry signal
  • "Stray light correction" algorithm (stray light ratio up to 0.01%)
  • Raman detection (wavelength 790~1010nm)
  • Long-time full-band (180~1100nm) measurement

EE (EagleEyeTM ) Series spectrometer, built with the Thermal Electric Cooler (TEC) sensor and high performance 32bits RISC controller in, is specially designed for long time measurement requirement. EE series contains a Thermal Electric Cooler (TEC) along with cooling system design to reduce dark current and maintain a lower stable operating temperature.

The optical engine is very simple and optimized for the spectrometer. The optical bench is very rigid and stable for measurement system, especially EE series has outstanding stability of thermo-hygro variation, vibration and shock on resolution and wavelength shift performance. The compact size is very flexible for system integration.
