The White Light Interferometer is a non-contact optical surface measurement system designed for high-precision analysis of surface roughness, step height, thin film thickness, and three-dimensional topography. Featuring sub-nanometer vertical resolution, a fully automated precision stage, and white light interferometry combined with phase-shifting techniques, the system provides accurate and reliable surface characterization for a wide range of materials. Its cost-effective design and ease of operation make it suitable for both research and industrial quality control applications.
Application
The White Light Interferometer is widely used for non-contact surface topography and dimensional measurements across multiple industries and material types.
Typical application scenarios and tested products include:
Aerospace components: surface roughness and step height measurement
Automotive parts: coated surfaces and precision machined components
Biomedical materials: surface morphology of bio-materials and coatings
Optical and glass products: lenses, glass substrates, transparent materials
Semiconductor industry: thin films, wafers, and micro-structured surfaces
Polymer and coating materials: film thickness and surface texture analysis
Pharmaceutical products: coated tablets and functional surfaces
Display panels: surface flatness and micro-topography inspection
Standards
The White Light Interferometer supports surface measurement and analysis methods aligned with commonly adopted international standards, including but not limited to:
(1) ISO 25178 – Geometrical Product Specifications (GPS): Surface texture – Areal
(2) ISO 4287 – Surface texture: Profile method – Terms, definitions and parameters
(3) ISO 5436 – Measurement of surface roughness standards
(4) ISO 16610 – Filtration of surface texture data
