Specific Wavelength Block Material

COMFOGUARD 

COMFOGUARD (UV, VIS, IR), specific wavelength block material developed by Fujifilm technology

COMFOGUARD is a material developed by Fuji Film by using silver - halide photograph fadeout prevention, color reproducibility, silver halogen emulsion fog suppression, astronomic photograph sensitive material, and near infrared light sensitization technology. This unprecedented material in powder form is able to block specific unwanted wavelengths selectively.

Can select light freely by 20nm

Wavelengths of light that can be block can be adjusted by 20nm units, enabling the selection of blocking wavelength range.

For example, visible lights between 460nm and 480nm contain wavelengths that are associated with sleep disorder. By using COMFOGUARD-VIS to cut off the wavelengths of this range, a material that prevents sleep disorder can be created. In addition, the degree of color can be maintained at a low level.

Processing method according to the purpose

COMFOFGUARD (UV, VIS, IR) is a material in powder form, and its type can be selected according to the purpose such as high solubility or high heat resistance. Therefore, this product can be applied to various processing methods such as coating or mixing with resin.
