In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens. In some embodiments, an optical window is disposed in the hollow chamber and is optically coupled to the output surface of the lens such that the light exiting the lens passes through the optical window before exiting the light module. In some embodiments, the shoulder can be formed as part of the housing. In other embodiments, the shoulder can be provided by a sleeve disposed in the module's housing.

A needle collection and counting tray for use in a clinical setting, such as an operating room, into which a user deposits used needles. The tray is then placed into a counting and identification machine the utilizes object recognition technology to identify and count the needles on the tray.

An optical waveguide package includes a substrate, and an optical waveguide layer on an upper surface of the substrate. The optical waveguide layer includes a cladding and a core in the cladding. The cladding has at least one first recess having a bottom surface and a first inner wall surface surrounding the bottom surface.

Laser light is coupled to optical fibers arranged in a sheet, which may be in the form of netting, mesh or fabric. Scattering centers or bends in the optical fibers allow the coupled light to escape from the sides of the fibers. Depending on the selection of wavelengths for the lasers, the resulting luminous sheet may be used for illumination of crops grown in vertical farms. The laser wavelengths excite plant photopigments for predetermined physiological responses, and the light source intensities may be temporally modulated to maximize photosynthesis and control photomorphogenesis responses. Each laser may be independently controlled, and at least one laser may emit ultraviolet-C radiation. The luminous sheet may be used for purification of air flowing through an air duct.

An aerosol-generating system comprises an aerosol-generating article having an indicium arranged on an outer surface thereof and an aerosol-generating device usable with the article. The aerosol-generating device includes a cavity, a heater, and an optical reader system. The cavity has an opening accessible at the outer body part and is configured to receive a consumable article comprising an indicium arranged on the article. The optical reader system includes at least one waveguide that has an incoupling surface, an outcoupling surface, and a detector. The waveguide is configured to illuminate the indicium in the cavity with a light beam and to transmit a reflected light beam provided by the indicium to the detector (30) of the optical reader system. A related method for authenticating a consumable article is also provided.
