Seed coating measurement solution - filmetrics F3-s1310 Film Thickness Measuring instrument

Seed coating refers to the process of evenly covering the surface of seeds with a seed coating agent containing various components such as insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents in a certain proportion by mechanical or manual methods, forming a smooth and firm film.

White light interferometry of dielectric films

Thousands of electrolyte films are used in optics, semiconductors, and other industries, and Filmetrics' instruments can measure films. Common dielectrics include: silicon dioxide - one of the simple materials, mainly because of its non-absorbency in most spectra (k=0), and it is very close to stoichiometry (that is, silicon: oxygen is very close to 1:2). Silica grown on heat has a spectral reaction specification and is usually used as a standard for thickness and refractive index. Filmetrics can measure the thickness of silica ranging from 3nm to 1mm.
