Examples of thin film evaluation

The evaluation of thin films is determined by the purpose for which the thin film is used. For example, if the thin film is used for enhancing mechanical strength, important factors for evaluation include hardness and adhesion. If the film is intended to impart optical properties, values such as reflectance and transmittance become significant. Our company strives to meet customer needs using evaluation equipment as listed below.
