FR-ES 370 - 1020 nm spectral range

Product description

The POLOS® FR-ES is a compact and light-weighted unit for the characterization of coatings. With FR-ES the user can perform reflectance and transmittance measurements in the 370 - 1700 nm spectral range. The FR-ES platform is designed to provide an excellent performance in terms of characterization of coatings.

The FR-ES can be employed in a wide range of diverse applications, such as: Film thickness, Refractive Index, Color, Transmittance, Reflectance, and many more. There are three configurations available: VIS/NIR (370 - 1020 nm), NIR-N1 (850 - 1050 nm), NIR (900 - 1700 nm).

Then, there is a wide range of accessories, such as:

  • Filters to block light at certain spectral regimes
  • FR-Mic for measurements at very small areas
  • Manual stage, either 25 x 25 mm or 100 x 100 mm or 200 x 200 mm
  • Film/Cuvette Holder for Absorbance / Transmittance and chemical concentration measurements
  • Integration Spheres for diffuse & total reflectance

By the combination of different modules, the final set-up meets any end-user needs.

White Light Reflectance Spectroscopy (WLRS) measures the amount of light reflected from a film or a multilayer stack over a spectral range, with the incident light normal (perpendicular) to the sample surface.

The measured reflectance spectrum, produced by interference from the individual interfaces is being used to determine the thickness, optical constants (n & k), etc. of free-standing and supported (on transparent or partially/fully reflective substrates) stack of films.
