ams has launched a tri-stimulus sensor which provides measurements of color that closely match the human eye’s response to the visible light spectrum. In addition, the new sensor also accurately measures blue-light wavelengths, which are linked to important health effects such as disruption or management of the circadian rhythm, accelerated eye aging, and eye strain. This lets manufacturers get to market quickly with emerging applications that address the interaction between light and human health.
Provided in a compact 4.5mm x 4.7mm x 2.5mm land grid array (LGA) apertured package, the AS7264N’s small size makes it well suited for luminaires and connected sensor packs; it is expected to be used in emerging applications of human-centric lighting and smart building control.
The new sensor is based on ams’ AS72xx product platform, and uses 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.
As stated in the announcement, “the AS7264N supplements that with two additional blue light filters, providing the capability to accurately measure the intensity of blue light at both the 440nm and 490nm wavelengths.”
“By incorporating an AS7264N into their product, lighting and building automation sensing solution manufacturers are able to deliver real-time smart color monitoring to measure and respond to end-users’ exposure to blue light wavelengths”, according to the firm.
“With true color sensing and precise spectral measurements at wavelengths with active photobiological influence, the AS7264N serves a wide range of applications including ambient light characterization and light exposure data collection for commercial, residential, and industrial lighting applications. This solution will help manufacturers get to market quickly with applications that address the interaction between light and human health,” said Tom Griffiths, Senior Marketing Manager for Lighting and Spectral Sensors at ams.
The AS7264N is available for sampling. Unit pricing is $4.50 in quantities of 1,000 units.
An evaluation board for the AS7264N color sensor is available from the ams ICdirect online store. For sample requests and more technical information, visit http://www.ams.com/Spectral-Sensing/AS7264.
