UV-Vis-NIR Spectroscopy

UV-VIS-NIR SPECTROPHOTOMETRY SERVICES

Ultraviolet-visible-near infrared (UV-VIS-NIR) spectrophotometry is used for reflectance (R) and transmittance (T) measurements across the ultra-violet, visible and near-infrared spectrum. UV-VIS-NIR spectroscopy is a robust analytical technique to determine the optical properties (transmittance, reflectance and absorbance) of liquids and solids. For example, UV-VIS-NIR spectrophotometry can assess the effectiveness of anti-reflective coatings for solar cells and uniformity of system response across the visible spectrum. 

APPlICATION AREAS FOR UV-VIS-NIR:

Companies in optics (components, coatings including anti-reflective, and high-reflection coatings), displays, solar, coatings, and semiconductors are frequent users of our UV-VIS-NIR spectrophotometry lab services.

MEASUREMENTS TAKEN FROM UV-VIS-NIR:

  • Optical constants:
    • Reflectance (R) and Transmittance (T)
    • Refractive index (n) and Extinction Coefficient (k) (accessible through modeling)
  • Film thickness 100nm-1um (~Å accuracy)

USES & LIMITATIONS OF UV-VIS-NIR:

  • What it is great for:
    • Excellent complement to Spectral Ellipsometry for collecting data for refined optical modeling
