Abstract
The present invention is directed to an assembly for use in detecting an analyte in a sample based on thin-film spectral interference. The assembly includes a light source to emit light signals; a light detector to detect light signals; a coupler to optically couple the light source and the light detector to a waveguide tip; a monolithic substrate having a coupling side and a sensing side; and a lens between the waveguide tip and the monolithic substrate. The lens relays optical signals between the waveguide tip and the monolithic substrate.
