Taiwanese-produced tungsten oxide (blue) for optical lenses (BTO)

High-purity BTO contributes to the improvement of lens coloring and optical properties.

In the optical lens industry, precise control of light transmittance and refractive index is required. Particularly for lenses with special optical properties, the selection of coloring materials is crucial, as optimizing light absorption and scattering significantly affects the performance of the lens. Inappropriate coloring materials can lead to a decline in lens performance and unwanted light reflection. Our tungsten oxide (blue) (BTO) presents a metallic blue color and contributes to enhancing the optical properties of lenses as a coloring agent for glass. 【Application Scenarios】 - Coloring of optical lenses - Adjustment of light transmittance - Control of refractive index 【Effects of Introduction】 - Improvement of lens optical performance - Vivid color reproduction - High durability
