METHOD OF MANUFACTURING A SPECTRUM ANALYZING SENSOR

摘要

The present invention provides a method for manufacturing a spectrum analyzing sensor (10) for example for fuel analysis in automotive applications. The method comprises obtaining a packaged optically active integrated circuit (13) comprising at least one optically active sensor (11) and a moulded package (14) with a package cavity (15) to create an optical window to the at least one optically active sensor (11), and attaching a discrete optical filter (12) for splitting a light spectrum in the package cavity (15).
