General description

The ams AS7343L1 is a 13-channel spectrometer designed for spectral identification of lateral flow test (LFT) markers. It is a highly versatile sensor targeted to enable new laboratory applications. It is optimized for reflective and transmissive measurements of colorization and fluorescent signals. Enabling applications like lateral flow test digitalization, fluid or reagent analysis, color matching, and other color changes relevant in diagnostic.

This product suits for the following applications:

  • Point of care diagnostics and home testing
  • Digitizing LFT and PCR home-testing
  • Detection of fluorescence and colorimetric dyes
  • Laboratory-grade color, liquid or reagent analysis
  • General purpose spectrometer tasks (spectral reconstruction)
