ams OSRAM AS7343 is a spectral sensor capable of matching the human eye’s perception of colour and light intensity. It is the company’s first product to combine 14-channel spectral analysis of visible and Infrared light (IR) with XYZ sensor technology to measure the colour and intensity of light as seen by the human eye. Automatic ADC reconfiguration also gives a faster multi-channel readout. The compact size of the sensors makes it easy to accommodate them in space-constrained applications. The AS7343 is suitable for colour analysis in applications which require frequent, accurate measurements such as in horticulture, smoke detection, etc.
According to the company, this multi-purpose sensor is ideal for colour analysis in applications which require frequent, accurate measurements. When integrated into colourimeters, portable spectrometers and consumer devices, the AS7343 gives added productivity, flexibility and functionality to users in applications for colour matching, lighting control, and spectral analysis. The sensor can be used to maximize the yield of plants by analyzing the colour and optimizing the spectral characteristics of horticultural lighting.
“The AS7343 provides a fast and accurate spectral measurement of light incident on the crop. These results may be matched with the light requirements of each plant species. Lighting settings can be adjusted to produce illumination at the relevant parts of the spectrum as necessary”, explains Kevin Jensen, Senior Marketing Manager in the Optical Sensors business unit at ams OSRAM.
The 14-channel AS7343 comes in a compact 3.1 mm x 2 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.
“With the AS7343 the user can perform quick sweeps of colour signatures of interest, or measure in full resolution, as needed. The sensor’s multi-channel capabilities also allow users to compensate for the human eye’s susceptibility to incorrect colour matching, called metamerism. This results in more accurate colour reproduction,” says Kevin Jensen.
The spectral sensor can be used for applications that include horticulture, smoke and heat alarms, consumer devices, etc.
