GHPMS-80 Sync-Skan SPECTRORADIOMETER

GHPMS-80 is a fast mechanical scanning spectrameter. It is the product of modern technologiesfor monochromators based spectroradiometer. GHPMS-80 has much faster speed than conventional monochromator based ones while the measurement accuracy is kept as high as originally. A typical measuring time during the spectral range from 380-800nm is only a few seconds comparing with several minutes of traditional scanning systems. Sync-Skan Speed the measurment largely.

Specifications:

  1. Sycn-skan technology is applied, and has faster test speed comparing with traditional scanning systems.
  2. A precise slit adjustment mechanism controlled by computer is set inside.
  3. Built-in wavelength calibration source.
  4. Spectrometer & Broadband-radiometer/photometer Combined Technique (SBCT) is adopted to enlarge the linear dynamic range.
  5. The calibration of spectral power distribution is directly traceable to NIST and NIM, superior accuracy can be achieved in UV-VIS-nIR measurement.
  6. Measure and display the relative spectral power distribution P(¦Ë), chromaticity coordinate(x , y)¡¢(u , v),correlative color temperature TC, rendering index Ra, Ri(i=1~15), color difference, peak wavelength, half width, color purity, dominant wavelength, red ratio, luminous flux etc.
