  • Page 32: Appearance Theory

    A glossmeter is used to quantify the amount of light reflected from a surface. At 20° the Rhopoint Detailometer uses a diode array to measure the distribution of reflected light +/- 7.25° from the specular reflection angle in steps of 0.02832°.

  • Page 33: Why Is Reflected Appearance Important

    The instrument provides goniophotometric profiles, gloss, haze and distinctness of image values which can be used to assess the visual qualities of any product. As well as assessing the visual impact of a surface, the Detailometer can also be used to identify problems associated with coating formulation and application.

  • Page 34: Gloss

    The Gloss Unit (GU) is defined in international standards including ISO 2813 and ASTM D523. It is determined by the amount of reflected light from a glass standard of known refractive index. Calibration tiles supplied with Rhopoint instruments are traceable to master glass standards held at NIST (Canada). www.detailometer.com...

  • Page 35: Measuring Gloss With The Rhopoint Detailometer

    20 degree - 2000GU = 100% reflectance So, 20 degree - 1000GU = 50% reflectance, 500GU =25% etc. When the Detailometer is calibrated in this mode it will calibrate to the GU value but will still display % reflectance. www.detailometer.com...

  • Page 36: Haze

    Haze is caused by microscopic surface texture which di uses light adjacent to the main component of the reflected light. When viewing the reflection of a strong light source in a surface with high haze the image “blooms” and has a bright halo around it. www.detailometer.com...
  • Page 37 Haze is an important measure for highly polished metals and is often associated with polishing marks and machining direction. Gloss-haze meters are traditionally used to measure this parameter and use a standard glossmeter design with additional light stops and diodes to measure the haze component 2° either side of the specular component. www.detailometer.com...

  • Page 38: Measuring Haze With The Rhopoint Detailometer

    Taking reliable readings with a traditional gloss-haze meter can be di cult as the sample surface needs to be completely flat and un-textured. The Rhopoint Detailometer automatically compensates for sample surface flatness and texturing allowing haze measurements to be taken on a much wider range of product surfaces.

  • Page 39: Haze Compensation

    This di use light exaggerates the haze signal for these surfaces causing higher than expected readings. The Rhopoint Detailometer compensates for reflection from within the coating for highly reflective pigments, metallic coatings and speciality pigments, allowing the haze of any painted surface to be measured.

  • Page 40: Corrected Haze Measurement On Metallic Coatings

    An advantage of the Detailometer is that unlike a conventional instrument, compensation is calculated using a region adjacent to the haze angle. This techniques gives compatible readings on solid colours but also compensates for directional reflection...

  • Page 41: Distinctness Of Image (Doi)

    finish was not as crucial. The Detailometer measures the DOI of a surface by quantifying the way a reflected measurement beam is spread and distorted around the specular angle.

  • Page 42: Reflected Image Quality (Riq)

    Reflected Image Quality (RIQ) Reflected Image Quality is a new measurement developed by Rhopoint Instruments to provide greater sensitivity when evaluating highly reflective coatings and the specular / di use element of lower gloss materials. Two highly reflective surfaces that have very small changes in orange peel or texture will show very little or no change in DOI due to the way that it is calculated but will appear quite di erent visually.
  • Page 43 The RIQ value of a surface is also a number between zero and one hundred; a surface that exhibits a perfect undistorted image returns a value of 100, as the values decrease higher surface texture is present and the image sharpness reduced. www.detailometer.com...

  • Page 44: Rspec- Peak Specular Reflectance

    IQ Reflectance 20° Gloss 89.1 logHzC 74.5 Rspec 57.7 The same paint applied to two panels, the second system has orange peel / waviness which is due to incorrect application setting on spray gun. RSPEC is shown by the red line. www.detailometer.com...
  • Page 45 Either of these e ects will cause readings errors using a standard glossmeter. To overcome this the Detailometer scans the reflectance profile of the surface from 12.75° - 27.25° and identifies the angular position of RSPEC. Gloss, Haze, DOI and RIQ values are then calculated using the RSPEC angular position as the 20°...

  • Page 46: Goniophotometric Profile

    Goniophotometric Profile The Gloss, Haze, DOI, RIQ and RSpec values produced by the Detailometer can be used to assess the visual quality of any surface. Alternatively, if required, the full Goniophotometric curves can be downloaded to PC for a detailed understanding of specular reflectance.

  • Page 47: Calculating Gloss, Haze, Rspec And Doi From A Goniophotometric Profile

    Calculating Gloss, Haze, RSpec and DOI from a Goniophotometric Profile , the Rhopoint Detailometer calculates the Gloss value For the above example at 20 by summing the gloss values +/- 0.9 from the specular angle. These methods / tolerances are specified in ASTM D523/ISO 2813.
