[Test Case] Ultra-precise film quality analysis of TiO2 optical thin films

Detailed explanation of the test results for multi-angular alumina particles/spherical silica particles.

We will introduce a case where optical films were tested using two types of particles: angular alumina particles and spherical silica particles, enabling an unprecedented level of ultra-precise analysis of film quality. The results from examining the angular alumina particles through an erosion rate (damage speed) distribution graph showed that "both the load at the time of impact and the contact area are extremely small, leading to concentrated force." 【Case Overview】 ■ Objective - To highlight slight differences in film quality using two types of testing conditions. ■ Test Results (Spherical Silica Particles) - Low hardness micro-spherical particles were used. - Although the load at the time of impact is large, the contact area is also large, resulting in dispersed force. *For more details, please refer to the PDF document or feel free to contact us.
