Gloss Meter
The Defelsko PosiTector Advance Body GLS Gloss Meter 20°/60°/85°. The degree to which a surface reflects light in a specular—or mirror-like—manner is known as its gloss. It has a major impact on how glossy or lustrous an object seems, which in turn affects how appealing it is to the eye and how valuable people think it is. Specular reflections are produced on highly gloss surfaces when light is reflected at the angle of incidence.
Gloss is typically measured and reported in Gloss Units (G.U.), following standards such as ASTM D523 and ISO 2813. Additionally, certain gloss meters, like the PosiTector GLS, can measure Reflectance and Haze Index. Reflectance quantifies the amount of detected light versus the amount sent, expressed as a percentage. Haze, on the other hand, refers to the milky halo or bloom seen in reflective surfaces due to microscopic imperfections. The 'Haze Index' is determined by subtracting the 20° from the 60° specular gloss measurements, as per ASTM D4039. Given the diverse range of gloss values, different measurement angles are employed to provide optimal resolution across matte, semi, and glossy samples.
