    摘要: Embodiments of the invention include a particle detection system that includes a light emitting source, a non-collimating reflector, a collimating reflector, and a detector. Light from the light emitting source is directed by the non-collimating reflector to an area through which a particle stream may be transmitted. Fluorescent light from the light striking particles is redirected to the collimating reflector and then on to the detector. Other embodiments include a single pump used to pull a pair of fluid flows through the detection system. Other embodiments include a plurality of light emitting sources whose light is directed to a particle stream by a single reflector. Other embodiments include a method for detecting particles.

    摘要: A lens and encapsulant made of an amorphous fluoropolymer for a light-emitting diode (LED) or diode laser, such as an ultraviolet (UV) LED (UVLED). A semiconductor diode die (114) is formed by growing a diode (110) on a substrate layer (115) such as sapphire. The diode die (114) is flipped so that it emits light (160, 365) through the face (150) of the layer (115). An amorphous fluoropolymer encapsulant encapsulates the emitting face of the diode die (114), and may be shaped as a lens to form an integral encapsulant/lens. Or, a lens (230, 340) of amorphous fluoropolymer may be joined to the encapsulant (220). Additional joined or separate lenses (350) may also be used. The encapsulant/lens is transmissive to UV light as well as infrared light. Encapsulating methods are also provided.
