US 2022/0179224 A1 · A TEST STRIP READER DEVICE AND A METHOD FOR DETECTING A TEST RESULT

Abstract

A reader device for detecting a test result from a testing element carrying a sample includes a radiation source for emitting electromagnetic radiation, an optical system for directing the electromagnetic radiation to the testing element, and a detector for receiving electromagnetic radiation from the testing element and for producing a detection signal responsive to the received electromagnetic radiation. The optical system includes a guide rod for conducting electromagnetic radiation and a lens system for focusing the electromagnetic radiation coming out via an egress-end surface of the guide rod to the testing element. The egress end-surface of the guide rod has an elongated shape so that a radiation pattern having an elongated shape is produced on the testing element. The elongated shape of the radiation pattern facilitates scanning the testing element with the electromagnetic radiation.
