Free QuoteSurface roughness definitions and standards The most common roughness specifications are peak-to-valley (PV) or root-mean-square (RMS) values. PV values are determined by finding the difference between the highest peak (y max) and lowest valley (y min) along a surface with height y; .
Surface roughness is a measure of high-frequency deviations in the departure of a surface from ideal. Surface roughness can result in unwanted scattering in an optical system and for many optical applications one might think it is always best to minimize surface roughness.
This publication was last reviewed and confirmed in 2023. Therefore this version remains current. This document specifies requirements of appearance, durability and safety, test methods and designation for laminated solar photovoltaic (PV) glass for use in buildings. This document is applicable to building-integrated photovoltaics (BIPV).
Surface roughness is measured through a variety of techniques. Some manufacturers have contact profilometers that physically touch the surface and measure the surface via a fine diamond tip and the oscillation of the lever arm. This technique typically measures along certain lines on the surface.
Surface roughness can result in unwanted scattering in an optical system and for many optical applications one might think it is always best to minimize surface roughness. However, simply minimizing surface roughness without regard to system wavelength and performance can result in increased costs and longer production times.
PV values are determined by finding the difference between the highest peak (y max) and lowest valley (y min) along a surface with height y; . PV values give a good idea of maximum surface variation that may occur and therefore can suggest a surface is much rougher than it is on average.
