1 Scope

This standard specifies the use of stylus surface roughness measuring instrument to measure flat panel display substrate glass surface roughness measurement method. This standard is applicable to the measurement of the surface roughness of the substrate glass for flat panel displays.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Stylus surface roughness measuring instrument. Stylusurfaceroughness measurementuring The probe slides along the contour on a portion of the surface to be measured, magnifying the unevenness of the lower surface and indicating that the amplitude of the magnification curve is the table Surface roughness range of the instrument. 2.2 Cut long wavelength longwavelengthcut-off λL Excluding natural factors, when the tracing contour curve is removed by the ripple factor of the high-pass wavelength filter, the amplitude decay rate becomes 75% of the wavelength. 2.3 Real profile curve realprofile The surface of the target object is intersected with a plane perpendicular to the surface (see Figure 1). Figure 1 Profile curve 2.4 Short-wavelength shortwavelengthcut-off λS Tracer profile curve by filtering the roughness factor of the low-pass wavelength filter, the amplitude decay rate of 75% of the standard value wavelength. ......
