The Spectroradiometer has following special features :

  • Measures radiation spectra in relative, energy (Watts), or quantity units (moles) and reflected and transmitted spectra
  • Ruggedized fiber-optic spectroradiometers
  • Designed for portability in a rugged aluminum enclosure without moving parts
  • Apogee exclusive cosine-corrected detector accurately measures low angle light
  • Calibrated measurement ranges from 300 to 1000 nm (NIST traceability) with less than 1.0 nm resolution
  • All-in-one package including software interface and is powered via USB cable from laptop or desktop computer

Spectroradiometer (For Applied Research)

SPECTRAL EVOLUTION Field Portable Handheld Spectrometers & Spectroradiometers are lightweight, battery operated and easy to move from project to project- perfect companion for many applications including mineral reflectance, vegetative studies, solar analysis and ground truthing of airborne hyperspectral analyses.

Our field portable, remote sensing units offer all of the advanced features of our lab units including:

  1. 100% linear photodiode array platform- with InGaAs and silicon detectors for best resolution and sensitivity @ 350- 2500nm ranges
  2. Fast, full spectrum UV-VIS-NIR measurements with one- touch operation- autoexposure & auto dark current shutter
  3. Diffraction grating / beam splitter optics- no moving gratings or trifurcated fiber optics to break in the field
  4. No internal fiber optics- allows maximum sensitivity and S/N ratio with higher performance direct FOV lens optics
  5. Industry standard optional SMA fiber optic connection for easy interchangeability
  6. Lightweight (7 lbs with slide-in LiIon rechargeable battery) and easy to carry
  7. Bluetooth interface for wireless operation

Features unique to SPECTRAL EVOLUTION Portables include:

  1. Li-Ion Rechargeable batteries (2 provided) with separate external charger for continuous, uninterrupted use
  2. Software for both Windows-based laptops and bluetooth- compatible personal digital assistant (PDA) for maximum flexibility
  3. Membrane control panel for stand-alone operation without a computer connection (includes flash memory to hold 500 scans)
  4. Snap-on battery-operated cooling fan option for stable performance in extreme high-temperature conditions
  5. Nylon carrying strap with sturdy, reinforced eyelets for added security
  6. Laser guide to aid in target sighting with foreoptics (Spectroradiometers only)
