Abstract
A sensor element for detecting an analyte in a fluid sample by optical probing comprises a translucent membrane with a front side defining a sensor surface for contacting a fluid sample, and a back side facing away from the front side. The sensor element has a reflective layer at the front side of the translucent membrane. An optical input port and an optical output port are connected to the back side of the translucent membrane. The sensor element further comprises an optical constriction element with a screen element arranged between the input port and the output port. The constriction element further comprises a reflective element arranged at the backside of the translucent membrane and facing towards the reflective layer, thereby defining a probing region, the probing region comprising pores extending from respective openings at the sensor surface into the translucent membrane.
