WebIQ 20/60. The Rhopoint IQ DOI 20°60° glossmeter also known as Rhopoint IQ measures not only gloss but also other image quality parameters such as DOI, Haze, and RSPEC , it is the only handheld instrument that profiles how light is reflected from a surface.. Standard glossmeters only measure how much light is reflected and are not sensitive to the effects … WebThe ability of a surface to reflect light without scattering is known as gloss. Using a gloss meter, gloss is measured by directing a constant intensity light beam at a fixed angle to the test surface and then by monitoring the amount of reflected light at the same angle. Different surfaces require different reflective angles. hassan yehia
