Setting the Standard in Precision & Portability from 320 – 2500 nm

Spectral Evolution’s UV-Vis-NIR spectrometers and spectroradiometers provide the best combination of high resolution and high sensitivity resulting in the most precise field portable instruments available on the market.

Short Description

Spectral Evolution’s range of field-portable spectroradiometer bundles set the standard in precision, reliability and portability for spectral radiance, irradiance and reflectance measurements in the range from 320-2500nm. The all-solid-state design has no moving parts and features a silicon array for the UV-VIS-NIR band, with either one or two InGaAs detector arrays for the SWIR band. For the highest sensitivity, the detector arrays are thermoelectrically (TE) cooled.

 

Key Features

  • Fast, full-spectrum UV-Vis-NIR measurements – 350-2500 nm with just one scan
  • Superior reliability in the field – 100% diode array optics with no moving parts
  • Freedom of movement with no cumbersome cables – Bluetooth connectivity
  • Lithium-ion rechargeable batteries for field use
  • Lightweight, rugged and field-proven
  • Field switchable optics for varying target sizes and measurement modes
  • Automatic exposure control and auto-shutter for error-free operation
  • NIST- traceable calibration for spectral radiance & irradiance measurements
  • Exclusive DARWin™ SP Data Acquisition and Analysis software for one-touch, full range spectroscopic analysis of samples
