Evaluation of transmittance and yellowing degree (yellowness) using a color difference meter.

Digitizing transparency and color into numerical data! Objectively evaluating transparency rate and yellowing degree!

This introduction covers the evaluation of transmittance and yellowing (yellowness) using a color difference meter. By making the product's constituent materials transparent and rich in color, necessary functional characteristics, artistic qualities, and design elements for the product's application are imparted. However, yellowing (discoloration) may occur due to the environment in which they are used, potentially compromising those characteristics. By quantifying transparency and color not through human visual perception but as numerical data, objective evaluation becomes possible. [Overview] ■ Principles of color difference measurement and acquired data (XYZ Yxy color space) - Light emitted from the light source passes through the transparent sample, and within the integrating sphere box, data on the transmitted wavelengths (transmittance) and converted color space data is obtained. *For more details, please refer to the PDF document or feel free to contact us.
