AS7341L Spectral Sensor

for Optical Read out of Lateral Flow Tests


  • Low power consumption (1.8 VDD operation)
  • Electronic shutter/external trigger functionality
  • External photodiodes to expand detection range
  • Ultra-low profile package (3.1 mm x 2 mm x 1 mm)

AS7341L1 is a 10-channel spectrometer for spectral identification and color matching for lateral flow and health-related devices. The spectral response is defined in the wavelengths from approximately 350 nm to 1000 nm.  8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photodiode without filter ("clear"). The device can be synchronized to external signals via pin GPIO and is perfect for Covid-19 Test Equipment.
