The THz device module includes: a substrate; a THz device disposed on a front side surface of the substrate, and configured to oscillate or detect THz waves; a cap covering the THz device being separated from the THz device, and comprising an opening formed at a position opposite to the THz device in a vertical direction of the front side surface of the substrate; and a sealing member covering the opening of the cap so as to seal the THz device in conjunction with the substrate and the cap. A distance from the THz device to the sealing member is within a near-field pattern to which an electric field of the THz waves can be reached without interruption from a surface of the THz device to the sealing member. The THz device module efficiently emits or detects THz waves from the opening, thereby suppressing upsizing of the cap.

Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position. The support member is further adapted to maintain the light detection device in an upright position when the bottom surface and the support member are in contact with a working surface and the support member is in the open position.

Various embodiments of a light detection device and a method of using the device are disclosed. In one or more embodiments, the light detection device can include a housing that extends along a housing axis between top and bottom surfaces. The device can also include a port that is adapted to receive a sample, and a door connected to the housing. The door can include an actuator portion adapted to selectively move the door between a closed position and an open position, and a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port.

A microchip has a rear face attached to a front mounting face of a support plate. An encapsulation cover for the microchip is mounted to the support plate. The encapsulation cover includes a front wall, a peripheral wall extending from the front wall and an inside partition extending from the front wall and between opposite sides of the peripheral wall. The inside partition passes locally above the microchip to delimit two cavities. A bonding material is interposed between encapsulation cover and the support plate and microchip. An end part of the inside partition of the cover, adjacent to the front face of the microchip, include an accumulation and containment recess that is configured to at least partly receive the bonding material.

A far infrared sensor package includes a package body and a plurality of far infrared sensor array integrated circuits. The plurality of far infrared sensor array integrated circuits are disposed on a same plane and inside the package body. Each of the far infrared sensor array integrated circuits includes a far infrared sensing element array of a same size.

The present invention relates to a space-based instrument which provides continuous coronal electron temperature and velocity images, for a predetermined period of time, thereby improving the understanding of coronal evolution and how the solar wind and Coronal Mass Ejection transients evolve from the low solar atmosphere through the heliosphere for an entire solar rotation. Specifically, the present invention relates to using a 6U spherical occulter coronagraph CubeSat, and a relative navigational system (RNS) that controls the position of the spacecraft relative to the occulting sphere. The present invention innovatively deploys a free-flying spherical occulter, and after deployment, the actively controlled CubeSat will provide an inertial formation flying with the spherical occulter and Sun.

A multi-optical axis photoelectric sensor includes: a pair of body-side packings which seal between a body housing and both side edges of a light transmissive plate; first packings which seal between caps and the side edges of the light transmissive plate, and between the caps and end portions of the light transmissive plate, and which are connected to the pair of body-side packings; and second packings which are integrally molded with the first packings, respectively, and which seal between the caps and the body housing.
