Non-contact Roughness Profiler

Non-contact roughness testers use optical or laser scanning to capture surface topography, recording changes in reflected light signals to calculate profile parameters. They are used to measure the surface texture of soft materials such as paper coatings and plastic films, avoiding contact damage.
Selection
When selecting, consider that the measurement range must cover the sample roughness values, and the optical resolution should match the detection requirements. Pay attention to the instrument's resistance to ambient light interference. For soft materials, laser diffraction types are preferred. Verify the validity of the instrument calibration certificate.

Roughness Measurement Instrument Selection: Contact vs. Non-Contact
This article introduces the differences between contact and non-contact methods when selecting a roughness measuring instrument.
Comparison of Selection Parameters for Stylus and Laser Roughness Measuring Instruments
Stylus-type roughness measuring instruments perform contact scanning to measure two-dimensional profile parameters in accordance with standards such as ISO 4287, while laser-based instruments utilize non-contact optical principles and refer to ISO 25178.
Contact angle measuring instrument measures the surface wettability of paper.
The contact angle goniometer evaluates wettability by measuring the contact angle of a liquid droplet on the surface of paper, based on the principle of Young's equation. The static drop method is commonly used for measurement, requiring control over sample flatness, environmental conditions, and droplet volume, while also considering the influence of surface roughness.

This article primarily explores how the surface roughness of the substrate affects the adhesion of coatings or bonds.
Paper smoothness and roughness
Paper smoothness and roughness are key parameters that describe the flatness of the paper surface, and they complement each other. Smoothness refers to the extent to which the paper surface approaches an ideal plane, while roughness reflects the amplitude and frequency of surface irregularities.
