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

In a line projector a diode-laser beam having an elliptical cross-section is projected onto a Powell lens which spreads the beam to form a line of light. Distribution of power along the line of light is adjusted by rotating the diode-laser beam with respect to the Powell lens.
