SPECTRAL EVOLUTION Spectroradiometers can be used to measure
absolute power levels of LEDs and other spectral devices. In this figure,
spectral irradiance of the
SPECTRAL EVOLUTION ILM-105 light source at
both high (red trace) and low (green trace) intensity settings was measured at
its fiber output using a SPECTRAL EVOLUTION SR-3500 Spectroradiometer.

SPECTRAL EVOLUTION laboratory SR-Series full range photodiode
array spectroradiometers display superior signal-to-noise ratio and
including:
  • Solar radiance and irradiance measurements
  • Solar simulator test and classification
  • LED, laser, light source metrology
  • Radiometric calibration transfer

The SR-Series delivers a range of models that provide the following
benefits:
  • High sensitivity with a high signal-to-noise ratio and an
    unmatched wide dynamic range
  • Fast and easy operation
  • Autoexposure, autoscaling, and auto dark shutter for fast,
    accurate, one-touch scans
  • Compact, lightweight design - easy to fit into your lab
  • NIST traceable calibration  for irradiance or spectral radiance
    measurements and calibration transfer
  • No internal fiber optics or movable gratings that can break,
    drift, or fail during mission critical experiments
  • Fiber optic or optional integrating sphere input
All SPECTRAL EVOLUTION spectroradiometers calibrated for solar radiance
have capabilities for generating a spectral match report for measuring class
performance as per IEC60904-9/ASTM E927-05. This is especially useful for
measuring the performance of continuous solar simulators.

solar irradiance measurement
Validate the class of any commercially available solar simulator using the SR-1100 Spectroradiometer
as per IEC60904-9/ASTM E927-05. The graph was generated using the easy-to-use DARWin SP Data
Acquisition and Analysis software included with each LR- and SR-Series Spectroradiometer. The red
trace demonstrates the simulated solar graph of AM1.5 Global Tilt as per ASTM specification (E892). The
black trace shows the actual measurement of irradiance as detected using the SR-1100 over its full
spectroradiographic range (320-1100nm). Built-in software routines automatically provide class status
as a function of wavelength (inset).

LED- Measurement: Rapid one-touch measurements of light emitting diodes can be obtained
using the SR-500 Spectroradiometer and the companion DARWin SP Data & Acquisition
Module included with each unit. Here, the SR-500 was used to measure irradiance levels of
commercially available red LEDs (red trace) and yellow LEDs (yellow trace) in two separate
experiments. Easy pull-down menus in the software allow users to superimpose graphs for
convenience

Q: What's the difference between a spectroradiometer and a spectrometer?  Which instrument should I buy?
Q: What's the difference between a spectroradiometer and a spectrometer?  Which instrument
should I buy?

A:  SPECTRAL EVOLUTION Spectroradiometers are factory calibrated with NIST-traceable
reference standards to measure spectral radiance and irradiance . They can also be used as
spectrometers to measure reflectance, transflectance, absorbance and transmission.  If you don't
need to measure absolute energy levels of your target, then we suggest purchasing a spectrometer.
