Example 9【Dyes for illumination sensors】

The wavelength sensitivity of the photo-sensitive elements of semi-conductors, which is used at the light receiving section of illumination sensors has a peak at the infrared region having longer wavelength than visible rays. It detects near-infrared rays which can’t be detected by the human eyes and mistakenly judges it as bright. By applying dyes filters which cut near-infrared rays, we can expect the properties near the spectral sensitivity of the eye.
In this dyes filter, our YKR Series near-infrared ray absorption dyes have been applying.
