  • BEAM-SHAPING LENS, BEAM-SHAPING ELEMENT, LIGHT SOURCE DEVICE FOR AN ENDOSCOPE, AND ENDOSCOPE
    Publication number: 20250098943
    Abstract: A beam-shaping lens includes a first surface including a smooth-shaped concave surface; and a second surface including a convex surface substantially similar in shape to the concave surface. The beam-shaping lens converts a first light beam that is parallel light incident on the first surface and having a light intensity distribution that continuously increases from an outer periphery toward a center, into a second light beam that has a flatter light intensity distribution than that of the first light beam.

  • Relay optical system for rigid endoscope
    Patent number: 11598947
    Abstract: A relay optical system 20 for a rigid endoscope includes a lens fixing frame 21 and a plurality of lenses 22. The lens fixing frame 21 has a plurality of tubular bodies 26. The plurality of tubular bodies 26 are joined coaxially to each other. The plurality of lenses 22 are located at positions other than a joint position jp of the tubular bodies 26 in an axis direction of the lens fixing frame 21. The plurality of lenses 22 are located in the lens fixing frame 21 so as to have a coincident optical axis. The plurality of lenses 22 do not include a cemented lens.

  • IoT data collection system, IoT data collection method, management device, management program, agent device, and agent program
    Patent number: 11140144
    Abstract: Provided is an IoT data collection system 100 including an agent device 10 configured to acquire IoT data, a management device 20 configured to manage the agent device 10, and a server device 30 configured to receive the IoT data from the agent device 10. The agent device 10 includes a first transmission unit configured to transmit an authentication activation key to the management device 20 at startup. The management device 20 includes a collation unit configured to collate a registered activation key and the authentication activation key, and a transmission unit configured to transmit an authentication agent ID to the agent device 10 when the collation result is matched. The agent device 10 further includes a second transmission unit configured to transmit the IoT data and the authentication agent ID to the server device 30.
