Tri-Stimulus Color Sensor Precisely Measures Blue Light

The AS7264N tri-stimulus sensor which provides measurements of color that closely match the human eye’s response to the visible light spectrum. Notably, the sensor also accurately measures blue-light wavelengths, which researchers have linked to important health effects such as disruption or management of the circadian rhythm, accelerated eye aging, and eye strain. Available in a 4.5 mm x 4.7 mm x 2.5 mm land grid array (LGA) apertured package, it is suitable for luminaires and connected sensor packs.

 

The AS7264N is based on the AS72xx product platform, which includes a complete family of light and color sensors from near-UV to near-IR for spectral and lighting applications. The family’s tri-stimulus color sensors use unique on-wafer silicon interference filters to create individual spectral channels matching the characteristics of the XYZ standard observer model as specified by the CIE 1931 standard. The AS7264N supplements that with two additional blue light filters, providing the capability to accurately measure the intensity of blue light at both the 440 nm and 490 nm wavelengths.
