  • Patent number: 11874476
    Abstract: According to various embodiments, a device may include a light-emitting diode (LED) to generate optical radiation at an operational wavelength with a divergent emission profile, such as a Lambertian emission profile, relative to a planar face thereof. A metalens may be positioned to modify the divergent emission profile of the optical radiation from the LED to have a modified transmission profile. The metalens may comprise, for example, a substrate and a two-dimensional array of passive pillars that extend from the substrate with a radially symmetric pattern of varying pillar diameters. The pillars may be spaced from one another according to a uniform subwavelength interelement spacing. The diameters of the pillars are selected as a function of the operational wavelength to provide a target phase gradient that modifies the divergent emission profile of the optical radiation from the LED to have the modified transmission profile.

  • Patent number: 11353681
    Abstract: An objective lens mount and a connection device are releasably connected. The connection device is part of an objective lens or an adapter. The objective lens mount has at least one abutment surface that cooperates with at least one counter abutment surface at the connection device. At least two V-shaped first positioning bodies with at least one positioning surface are arranged such that the positioning surfaces face the longitudinal axis. At least one counter positioning surface at the connection device abuts the positioning surfaces of the objective lens mount. The relative position in the circumferential direction is defined via a rotation stop of the objective lens mount that cooperates with a counter rotation stop of the connection device. A locking device retains the connection device at the objective lens mount and effects a force component in the axial direction and preferably a force component in circumferential direction.

  • Patent number: 11076075
    Abstract: A lens assembly includes a lens housing, a flexible washer, and a lens module. The flexible washer and the lens module are disposed within a tubular sidewall of the lens housing. The washer is disposed axially between a mating surface of the lens module and a base surface of the lens housing. The lens housing and lens module include corresponding threads, and rotation of the lens module along the threads of the lens housing adjusts the axial position and focus of the lens module. The washer is the only component axially between the lens module and the lens housing and directly contacts the base surface and the mating surface. When compressed, the washer exerts an axial force on the lens module and lens housing, such that the friction on the threads is increased and the lens module is held in place.
