Optically Filtering Adhesive Film
Product Overview
This adhesive film absorbs specific wavelengths in the range from UV (ultraviolet) to visible light. The absorption wavelengths can be controlled according to the application, such as enhancing the color reproducibility of displays or preventing degradation through UV cut. It is suitable for a wide range of optical applications, including displays, touch panels, optical devices, and automotive equipment.
