New AS7343 multi-spectral sensor adds XYZ technology to increase speed and accuracy of color measurements

ams OSRAM has extended its broad portfolio of spectral sensors with the launch of the AS7343. It is the company's first product to combine multi-channel color analysis with XYZ sensor technology to measure the color and intensity of light as seen by the human eye. When integrated into colorimeters, portable spectrometers and consumer devices, the AS7343 gives added productivity, flexibility and functionality to users in applications for color matching, lighting control, and spectral analysis.

This new multi-purpose sensor is ideal for color analysis in applications which require frequent, accurate measurements. For instance, operators of greenhouses and indoor farms use color analysis to optimize the spectral characteristics of horticultural lighting, and to maximize yield and energy efficiency. Different crops’ growth is stimulated by different parts of the visible light spectrum.

The 14-channel AS7343 is chip housed in a flat 3.1 mm x 2 mm x 1 mm package. It functions like a spectrometer, measuring the spectral power distribution of a light source or reflected light. It features 12 equally spaced measurement channels in the visible light spectrum, alongside a Near Infrared (NIR) channel and including the XYZ function (more info).
