Dorigon or DORIGON?


FAQ: "Can you give me the correct spelling for Dorigon, please?"

It is exactly as you have it – “Dorigon”, although I seen it in caps – DORIGON. There are a couple of versions, I and II, but all the same basic sensor originally built by HunterLab.

Dorigon stands for Distinctness of Reflected Image Abridged Goniophotometer in case you are wondering…

It is the name of a legacy instrument built in conformance with ASTM E430 that could measure specular gloss at 30 degrees but was primarily intended to measure reflected scattering as DOI – distinctness of reflected image/orange peel; 2⁰ and 5⁰ reflected haze on mirror-like surfaces, along with 15⁰ diffuseness for surfaces like brushed aluminum.

Industrial Method and References

The primary reference for the Dorigon is:

  • ASTM E430 Measurement of Gloss of High-Gloss Surfaces by Abridged Goniophotometry

Application and Use of DOI – distinctness of reflected image/orange peel; 2⁰ and 5⁰ Reflected Haze and 15⁰ Diffuseness for is referenced in:

  • ASTM D4039 Standard Test Method for Reflection Haze of High-Gloss Surfaces
  • ASTM D5767 Standard Test Methods for Instrumental Measurement of Distinctness-of-Image Gloss of Coating Surfaces

ASTM - American Society of Testing and Materials, West Conshohocken, PA USA
