    摘要: Systems are provided for a modular multi-wavelength UV-VIS detector unit, such as an absorbance detector (e.g., spectrophotometer) included in a high-performance liquid chromatography system. In one example, a detector unit includes one or more light emitters and a sliding assembly configured to slidingly move a flow cell relative to the one or more light emitters, the one or more light emitters mounted on a floating rig to facilitate alignment between the one or more light emitters and the flow cell when the sliding assembly is in a closed position.

    摘要: A radiation monitor for a lighting device, and operating methods and systems therefor are provided. In one example, a radiation monitor may include a first sensor receiving radiation output directly from a light-emitting element of the lighting device and radiation output from external sources; and a second sensor receiving the radiation output from the external sources without receiving the radiation output directly from the light-emitting element of the lighting device. The radiation monitor may determine an intensity of the radiation output directly from the light-emitting element based on a difference in the output signals from the first sensor and the second sensor.

    摘要: A curing device comprises a first elliptic cylindrical reflector and a second elliptic cylindrical reflector, the first elliptic cylindrical reflector and the second elliptic cylindrical reflector arranged to have a co-located focus, and a light source located at a second focus of the first elliptic cylindrical reflector, wherein light emitted from the light source is reflected to the co-located focus from the first elliptic cylindrical reflector and retro-reflected to the co-located focus from the second elliptic cylindrical reflector.

    摘要: A method of irradiating a work piece may include forming a cutout recessed from a surface of a light guide, positioning the work piece inside the cutout, irradiating a light input surface of the light guide with UV light, and guiding the UV light from within the light guide through recessed surfaces of the cutout to irradiate the work piece. In this way more uniform irradiation of all curable surfaces of a work piece may be achieved, the energy and time consumed during irradiation of the work piece may be reduced thereby lowering operating costs, and the radiation delivery system may be made more compactly, thereby making it more convenient and practical for daily applications.

    摘要: Systems and methods for operating one or more light emitting devices are disclosed. In one example, the a negative temperature coefficient control parameter is applied to an amplifier to adjust a gain of the amplifier so as to provide a substantially constant level of irradiance output from one or more light emitting devices.

    摘要: A method for example of irradiating a light-curable material, may comprise irradiating light about a first axis from an array of light-emitting elements towards a light-curable surface, directing the irradiated light through an optical element interposed between the array of light-emitting elements and the light-curable surface, wherein a central axis of the optical element is offset from the first axis, and deflecting the irradiated light directed through the optical element asymmetrically away from the first axis towards the light-curable surface.
