Optical functions

Optical functions

We offer a variety of materials with properties that can be harnessed to extract optical functions.
We use particles with small particle size and sharp particle distribution, enabling us to produce low-haze, high-transparency materials.

Light diffusing particles are composite particles with unique structures, and present various light diffusion effects.

Adjustment of refractive index

We provide a rich product lineup ranging from products with low refractive index to products with high refractive index.
The surface properties can be adjusted to match the coating base materials.

Description	Product name
Materials with low refractive index	THRULYA
Materials with high refractive index	OPTOLAKE（Titanium oxide type sol） ELCOM V-4566
Refractive index adjustment material	OPTOLEKA（n=1.60） OPTOLEKA（n=1.67） OPTOLEKA（Primer coating） Electrode protective materials for use in touch panels

Anti-reflection

We provide anti-reflection film produced by combining film with low refractive index and film with high refractive index.
The large difference in the refractive index of the materials combined allows us to achieve low reflection factor.

LR paint

UV absorption/UV cutting

We offer UV absorption materials made from titanium oxide.
They can be used in cosmetic products and for industrial applications. It is possible to improve effectiveness through the combined use with UV diffusion materials.

Light diffusion (soft focus)

Structures with different refractive indices are present in the particles.
We have a lineup of composite particles that offer various effects and results.

Materials that are effective for changing colors

We provide particles with color-flopping effects that change the color depending on the viewing angle.
