Make Image Clearer and More Vivid

The Optical Information Business Unit supplies core optical components for camera modules and related absorption materials based on various independently developed absorption materials.

01 IR Cut-off Filter

The IR Cut-off Filter blocks infrared light and only allows visible light to pass through, which helps to make the image captured by the image sensor more similar to what is seen by the human eye.
