    • An optical detector (1) acts as a modular detection unit. It may for example be mounted on a separate micro-fluidic device (2) for detection of species within a channel (3) of the device (2). The detector (1) has mounting lugs (4) for mounting on the micro-fluidic device (2) for exact registry with the channel (3). A substrate (15) is folded over at a flexible part (25) through 180° and, at the top, supports a vertical emitting laser device (16). The lower branch of the substrate (15) supports an integrated circuit photo-diode array sensor (17) having chip bumps (18). The substrate (15) also supports emitter drive circuitry (26) and detector circuitry (27). The sensor (17) is a silicon integrated circuit, having an array of integrated photo-diodes (17(a)) in a silicon wafer (17(b)). There is a vertical through-hole (17(c)) in the wafer, to act as a guide for incident radiation emitted by the emitter (16) (arrows IR). Because of the single folded-over substrate arrangement the emitter 16 can be particularly easily and accurately aligned with the guide aperture 17(c).
    • 光检测器(1)用作模块化检测单元。 其可以例如安装在单独的微流体装置(2)上,用于检测装置(2)的通道(3)内的物种。 检测器(1)具有用于安装在微流体装置(2)上用于与通道(3)精确对准的安装凸耳(4)。 衬底(15)在柔性部分(25)上折叠180°,并且在顶部支撑垂直发射激光装置(16)。 基板(15)的下部分支撑着具有芯片凸块(18)的集成电路光电二极管阵列传感器(17)。 衬底(15)还支持发射极驱动电路(26)和检测器电路(27)。 传感器(17)是在硅晶片(17(b))中具有集成光电二极管阵列(17(a))的硅集成电路。 在晶片中存在垂直通孔(17(c)),以用作由发射器(16)发射的入射辐射(箭头IR)的引导件。 由于单个折叠的基板布置,发射器16可以特别容易且精确地与引导孔17(c)对准。
