General Description
The ams OSRAM AS7343L1 is a 13-channel spectrometer designed for spectral identification of lateral
flow particle markers. It is highly versatile sensor targeted to enable new laboratory applications. It is
optimized for reflective, transmissive and emissive measurements including lateral flow test
applications, fluid or reagent analysis, color matching, and spectral identification in the visible range.
13 individual channels cover the spectral range from approximately 380 nm to 1000 nm. 11 channels
are centered in the visible spectrum (VIS), plus one near-infrared (NIR) and a clear channel. Allowing
a full spectral re-construction of the incoming light.
AS7343L integrates high-precision optical filters onto standard CMOS silicon via deposited
interference filter technology. A built-in aperture controls the light entering the sensor array to increase
accuracy. A programmable digital GPIO and LED driver enable light source and trigger/sync control.
Device control and spectral data access is implemented through a serial I²C interface. The device is
available in an ultra-low profile package with dimensions of 3.1 mm x 2 mm x 1 mm.
Applications
Multi-analyte detection
Fluorescent-based measurement applications
Luminescence-based measurement applications
Reflection- or transmissivity-based color detection (e.g. lateral flow strips)
