IRCF

The manufacturing process for image sensor filters, and IR cut-off filters consists of deposition, printing, dicing and inspection processes. Filters are depositioned repeatedly with high refractive index and low refractive index material, reducing residual stress and crack on the thin films to ensure reliability and yield of optical devices. In particular, the image sensor filters strictly manage the inflow of fine dust from outside in the manufacturing stage, and also have an automated high-speed AVI (automatic visual inspection) system that can strictly inspect fine dust and defects smaller than 10μm.
