  • Patent number: 10436639
    Abstract: A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).

  • Patent number: 10312569
    Abstract: A surface-mounted signal transceiver module with multi-signal feed-in includes an antenna unit, a circuit board and a signal-integrating component. A radiation layer is arranged on a substrate-front face of the antenna unit. A ground layer is arranged on a substrate-back face. A first-feed-in line and a second-feed-in line are arranged on a substrate-side face. A first-ground face arranged on a circuit-board-front face of the circuit board is connected to the ground layer. A first contact and a second contact of the circuit board are connected to the first-feed-in line and the second-feed-in line respectively, and electrically connected to a fixing-connecting area arranged on a circuit-board-back face. The signal-integrating component is electrically connected to the fixing-connecting area, and connected to the first-feed-in line and the second-feed-in line through the first contact and the second contact respectively, to integrate signals sent through the first-feed-in line and the second-feed-in line.
