Chemistry & Materials
Chemistry and materials industries increasingly rely on precise surface characterization techniques: coating analysis, treatment evaluation, thin film measurement and local mechanical behavior assessment. Altimet provides non-contact optical topography instruments suited to these needs, in both R&D laboratory and industrial environments.
Combining chromatic and interferometric sensors, our AltiSurf© systems characterize a wide range of materials — metals, polymers, ceramics, coatings — with nanometric resolution.
Optical Metrology for Chemistry and Materials
Materials characterization requires tools capable of precisely measuring fragile, reflective or complex microstructure surfaces. AltiSurf© systems combine multiple optical measurement technologies to meet the demands of both research and production environments.
Indentation — Hardness and Local Mechanical Behavior
Analysis of an indentation trace provides valuable information on the mechanical properties of a material. Our instruments precisely measure the residual depth of the indentation and the volume of material displaced around the contact point. This data enables evaluation of local hardness, elasticity and ductility — essential parameters for qualifying coatings, heat treatments or novel materials.
Shot Blasting — Characterization of Treated Surface Condition
Shot blasting is a widely used surface preparation process to improve coating adhesion or modify the tribological properties of a part. Altimet characterizes the resulting surface condition using ISO 25178 standardized parameters: roughness, peak profile, peak density. An objective and reproducible measurement to validate processes and guarantee surface treatment quality.
Thin Film Analysis — Thickness and Coverage
Measuring thin films deposited on a substrate is a recurring challenge in chemistry and cosmetics. Our instruments measure the thickness of very thin deposits — creams, varnishes, inks, functional coatings — by mapping the surface topography before and after deposition. The example of sunscreen thickness measurement on a PMMA skin replica illustrates the sensitivity and versatility of our systems on substrates with high surface variability.
