Contact Probe with High Intensity Light Source for Reflectance Measurements

Lawrence, MA – March 19, 2019 – The SPECTRAL EVOLUTION standard contact probe is designed for mineral identification and soil analysis. This lightweight and comfortable probe measures surface reflectance from 350-2500nm. The probe features a new high intensity bulb to provide a focused and more intense light source for contact measurements. The probe provides improved signal to noise ratio for measurements in critical areas of the spectrum. Other features include:

  • 10mm spot size
  • Unique, comfortable low reflectance, impact resistant ABS thermoplastic handle
  • Light touch, tactile feel, pushbutton trigger for data collection
  • Metal clad fiber optic cable with quick disconnect
  • Lightweight, easy to carry and easy to hold and use all day
  • Plugs directly into SPECTRAL EVOLUTION quick release fibers for our spectrometers or spectroradiometers
  • Scratch resistant crystal and rubber gasket protect the probe window for clear and accurate measurement
  • Ideal for mineral reflectance studies of any kind and soil analysis in the field

The compact probe works with the oreXpress, SR-6500 and RS-5400 spectrometers for mining exploration, core logging and chip tray analysis and the PSR+, RS-5400 and RS-3500 for soil analysis.
