A system for irradiating a microplate may include a modular light engine with one or more light emitting devices. The light emitting devices are configured to emit germicidal radiation to irradiate the microplate, which is configured to be positioned below the modular light engine inside a chamber of the microplate irradiation system. In this way, a uniform intensity of germicidal radiation may be output by light emitting devices, resulting in disruption of contaminating nucleic acids present in the microplate.

Systems and methods for bio-inactivation

A liquid chromatography flow cell including an integrated light source and an integrated detection chamber. The integrated light source includes a plurality of light emitting diodes (LEDs), wherein each LED emits light of a specific wavelength. The light emitted from the integrated light source is directed to pass through a sample in a flow chamber of the flow cell without any optical conditioning, and the light not absorbed by the sample flows out of the flow chamber directly into the integrated detection chamber, where an intensity of the unabsorbed light is measured by detectors coupled to the integrated chamber.

Integrated illumination-detection flow cell for liquid chromatography

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.

Pivoted elliptical reflector for large distance reflection of ultraviolet rays

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.

Methods and system for thermo-optic power monitoring

A method may comprise: supplying light energy from a light emitting device principally along a first axis; sensing the light energy with a light sensing device oriented along a second axis, wherein the second axis is oriented substantially orthogonally to the first axis; and adjusting the light energy in response to the sensed light energy. In this way, an amount of retro-reflected light incident at the light sensing device may be reduced, measurement error of the light sensing device may be reduced, and control precision and reliability of the lighting system for curing a work piece can be increased.

Lighting system and methods for reducing noise at light sensing device

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.

Radiation delivery system and method

Methods and systems are provided for a lighting module and related components for efficiently directing dissipated heat and/or heated air away from the lighting module. Deflectors are often used to funnel heat away from solid-state light emitters and channel airflow away from a curing surface, but the risk of constrained airflow may negatively affect emitter output as well as disturb the curing process of a workpiece emitted light is directed towards. To efficiently remove heat as well as not disturb the curing process or shape of the lighting module, louvered vents are provided that extend into an interior of a housing of the lighting module for guiding heated air in a deflecting direction away from the emitted light direction.

Internal deflection venting

A curing device may comprise a first array of LED's, each LED of the first array emitting radiation substantially centered at a first excitation wavelength onto a quantum dot layer, the quantum dot layer positioned above the first array of LED's and configured to partially absorb the first excitation wavelength radiation and down convert the absorbed first excitation wavelength radiation, and partially transmit the emitted first excitation wavelength radiation, wherein the down converted and the partially transmitted first excitation wavelength radiation are directed onto a radiation-curable workpiece.
