Visible Light Absorption Materials

Yamada Chemical's visible light absorption materials can selectively absorb light at specific wavelengths in the visible light range (400-750nm). These materials are being considered for a variety of applications, including optical filters for display products and devices, as well as organic solar cells.

We propose dyes that meet customer needs, such as durability (light resistance, heat resistance), high transparency, and high solubility.

We offer a variety of half-widths, from sharp to broad, to meet a variety of needs.

Areas of Use

Various filter applications, color filter applications, optical recording applications, ink / toner applications,

UV absorption / blue light cut applications, electrochromic applications, organic solar cell applications, etc.
