Sensor óptico e método para medir luz irradia de um analito mediante excitação da luz, e, kit de partes

摘要

The invention provides an optical sensor (100). The optical sensor (100) comprises a planar waveguide (120) capable of emitting radiation (22) in a direction perpendicular to the sensor waveguide surface (122) and capable of accepting and transmitting radiation (16) to detector (140), preferably a planar detector (140). Further, optionally one or more lenses (133), one or more spectral filters (131) and one or more polarisation filters (132) may be arranged between the waveguide (120) and the detector (140). The optical sensor (100) is especially arranged to read out a wire grid substrate (200) with analytes (10).
