摘要： Methods and systems are provided autofocusing an imaging system. In one example, a method includes identifying a target focal plane of a field-of-view (FOV) of each objective of the imaging system, the imaging system including two or more objectives, adjusting a vertical position of each objective relative to the target focal plane based on a light shape generated from a laser beam, and aligning a focus of each objective according to a power level detected by a sensor.

摘要： Methods and systems are provided for separating polarized UV light. In one example, a method may include passing polarized source light through a group of at least four prisms to collimate and separate a second-harmonic generation (SHG) beam from a pump beam. The separated SHG beam may then be further passed through a spatial filter to reduce spatial distribution.

摘要： Methods and systems are provided for an adaptive illumination system. In one example, an adaptive illumination system comprises an adaptive illuminator comprising at least three optical elements including a first optical element, a second optical element, and a third optical element, wherein a distance between the first optical element and the second optical element is adjustable.

摘要： Systems and methods for achieving increased irradiation and/or illumination in a photo reactive system is disclosed. In one example, a photo reactive system includes a light source, a refractive cylindrical optic, and a curved reflector. By utilizing the refractive cylindrical optic, angular spread of the light source is reduced, which in turn reduces a size of the curved reflector for directing the light rays onto a work piece. Consequently, a more compact photo reactive system with higher irradiation and/or illumination capabilities can be achieved.

摘要： A system for irradiating a microplate may include a light engine with a plurality of light sources, such as light-emitting diodes, included in one or more linear arrays. The plurality of light sources are configured to emit germicidal irradiation, which is directed to the microplate by optical components, such as optical lenses positioned on top of each well of the microplate. The linear array is linearly movable so that as the linear array scans across the microplate, the optical components direct the germicidal irradiation to a plurality of surfaces of each well.

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： Systems are provided for a frame of an optic element of a lighting system. In one example, a baffle frame including extended exterior sidewalls and inner angled walls extending below a bottom surface of the optic element may reduce light reflecting off a workpiece and escaping outside and interior of the baffle frame.

摘要： A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.

摘要： Systems and methods are provided for a UV-VIS spectrophotometer, such as a UV-VIS detector unit included in a high-performance liquid chromatography system. In one example, a system for the UV-VIS detector unit may include a first light source, a signal detector, a flow path positioned intermediate the first light source and the signal detector, a second light source, and a reference detector. The first light source, the signal detector, and the flow path may be aligned along a first axis, and the second light source and the reference detector may be aligned along a second axis, different than the first axis.
