Spectral Sensor Can ID Paint Swatches

March 15, 2023
Using one of ams OSRAM’s six-channel spectral sensors, a company created a handheld spectrometer that can ID paint color names from a number of paint manufacturers.

ams OSRAM is big into imaging and sensors. Jim Archibald, Senior Engineering Manager, showed me the company's new compact color sensor (see video above). The demo utilizes Variable's Color Muse, which contains a six-channel ams OSRAM spectral sensor (see figure)

The Color Muse smartphone application collects colors detected by the sensor and matches them to photos. Such a tool can be very handy for everyone from professional painters to graphic designers to interior decorators. 

The ams OSRAM AS7262 is a smart six-channel, consumer-grade visible spectrum (VIS) sensor. It handles visible wavelengths from approximately 430 to 670 nm with full-width half-max (FWHM) of 40 nm. The chip includes an integrated LED driver with programmable current for electronic shutter applications.

The system, which integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology, comes in a LGA package that provides a built-in aperture to control the light entering the sensor array.
