Thin film thickness measurement is often difficult because the coatings are thin, visually subtle, and sometimes applied to complex shapes or sensitive surfaces. In many applications, functional coating thickness directly affects corrosion resistance, adhesion, conductivity, durability, or final product performance.
Small thickness differences can materially affect coating function, especially on protective, ceramic, adhesive, or specialty layers.
Parts with curves, edges, recesses, and formed surfaces are harder to inspect consistently with traditional manual methods.
Contact-based inspection is not always ideal when surfaces are delicate, tightly controlled, or difficult to access.
A few spot checks do not always show local variation, subtle drift, or coating distribution across the full part surface.
For manufacturers trying to improve coating repeatability, validate functional performance, or support thin film metrology workflows, non-contact coating thickness measurement can provide much more useful data than manual checks alone.
AIM Systems uses a photothermal coating thickness measurement principle to determine coating thickness without contacting the surface. For thin films and functional coatings, this makes the system attractive where repeatability, mapped data, and protection of the measured surface are important.
The CoatPro platform can be used in applications where discrete parts, components, or technical surfaces need more structured measurement than simple spot checks can provide. This is particularly relevant for advanced materials, aerospace parts, specialty process layers, adhesive coatings on components, and other non-web applications.
Ethernet communication, Modbus TCP PLC integration, Power-over-Ethernet, and multiple measurement modes help the system fit into engineering labs, automated inspection cells, and more structured production data workflows.
If your team is trying to move from limited spot checks toward more repeatable thin film data or mapped functional coating inspection, this is the type of architecture worth evaluating.
For a deeper technical explanation of how this measurement method works, see our guide to photothermal coating thickness measurement technology.

Thin film and functional coating thickness measurement is especially relevant where coating performance, process repeatability, or surface sensitivity make manual inspection less effective.
Functional and protective coatings on technical parts where coating performance and repeatability are important.
Discrete parts and assemblies with technical thin films, ceramic coatings, or specialty protective layers.
Adhesive coatings on rubber or technical components where controlled layer thickness affects performance or downstream assembly.
Engineering teams working on coating repeatability, validation, thin film metrology, and improved inspection workflows.
If the goal is better thin film process understanding, fewer quality escapes, or more confidence in functional coating repeatability, this category is often worth evaluating.
