SP-85 Spectrometer / Spectroradiometer


SP-85 Spectrometer Spectroradiometer

SP-85 Spectrometer Spectroradiometer

  • Spectral Irradiance
  • CIE 1931 (x, y) and 1976 (u’, v’)
    chromaticity coordinates
  • Dominant Wavelength
  • CCT and CRI
  • LED Measurement
  • VIS Light Measurement
  • UV Light Measurement
  • Lamp Measurement
  • Fiber Optic Illumination Measurement
  • Spectral Radiant Flux (as a component of the LMS-SP85-X light measurement system)
  • Luminous Flux (Lumens) (as a component of the LMS-SP85-X measurement system)

The SP-85 spectrometer /spectroradiometer offers the highest sensitivity, low noise, and fine optical resolution. The SP-85’s sensitivity makes it ideally suited for high-speed, triggered single pulse or PWM calibrated spectral irradiance measurements, or radiant flux measurements when combined with an integrating sphere and calibrated (this combination is offered as our LMS-SP85-X light measurement system).

Stray light calibration and correction is available as an additional service on all SP-85 models.
