Abstract: 7,660 APPARATUS AND METHOD FOR MEASURING THE DISTRIBUTION OF RADIANT ENERGY PRODUCED IN PARTICLE INVESTIGATING SYSTEMS In an apparatus in Which particles are passed through an optical sensing zone to measure their radiant energy distribution such as, for example, light scattering characteristics for the purpose of identifying the particles, means and a method are provided for deviating the collected light in accordance with predetermined different paths to a plurality of different photodetecting devices. The deviation is effected independently of collection by optical radiant energy transmitting or reflecting means. The different photodetecting devices enable the measurement of energy directed along the particular path which is identified with that device. The paths are established by the deviating means rather than permitted to evolve by the scattering phenomena themselves whereby the photodetecting devices can be located in convenient arrangements and may be conventional in construction. Different forms of the invention combine optical reflection or refraction for collecting the scattered radiant energy with optical reflection or refraction for deviation to achieve different advantages and results. -1-.

Abstract: In an apparatus in which particles are passed through an optical sensing zone to measure their light scattering characteristics for the purpose of identifying the particles, means and a method are provided for deviating the collected light in accordance with predetermined different paths to a plurality of different photodetecting devices. The deviation is effected simultaneously with collection by optical radiant energy reflecting means. The different photodetecting devices enable the measurement of energy scattered along the particular path which is identified with that device. The paths are established by the combined collecting and deviating means rather than permitted to evolve by the scattering phenomena themselves whereby the photodetecting devices can be located in convenient arrangements and may be conventional in construction.

Abstract: A particle analyzing apparatus comprising a reflector chamber containing an electrolyte and having a concave reflector surface with a first focus and a second focus; entraining structure, having an introduction tube for providing and moving a stream of particles suspended in an electrolyte solution through the first focus; a source of radiant energy for illuminating the particles as they pass through the first focus to produce a source of detectable radiation signals, which reflect off the concave reflector surface to be subsequently collected and analyzed; an exit tube coaxially aligned with the introduction tube; a sensing orifice mounted in the tip of the introduction tube or the exit tube; and a pair of energized electrodes disposed in the electrolyte solution on either side of the orifice, whereby the orifice creates a constricted electrical path in which the stream of particles generate electrical impedance signals as they move therethrough.

Abstract: REDIRECTING SURFACE FOR DESIRED LIGHT INTENSITY PROFILE An optical device for redistributing incident radiation, such radiation having a non-uniform intensity distribution. The resultant redistributed radiation having a narrower desired intensity distribution in a predetermined region of an output plane. The optical device comprises a redirecting surface of a lens or reflector, for relocating at least a portion of the incident light. In one application, particles are illuminated in the output plane. The redirecting surface has a central portion and a peripheral portion, each said portion being disposed and configured to receive part of the incident radiation. The central portion is constructed to permit the incident radiation to irradiate the predetermined region of the output plane, and the peripheral portion is constructed to redirect specific rays of the incident radiation to specific locations in the predetermined region of the output plane, whereby the specific locations are further irradiated so as to create the desired intensity distribution within the predetermined area.

Abstract: Disclosed is a radiation collector apparatus for analyzing particles by irradiating the particles to produce a source of detectable radiation, wherein the radiation collector apparatus comprises a reflector chamber having a half ellipsoidal first reflector surfaces and a second reflector surface in the form of a planar reflector surface or a half ellipsoidal surface. Detectable radiation emanating from a primary focus of the first reflector surface either directly or after one or more reflections proceeds through a window formed in one of the reflector surfaces for subsequent processing. In another embodiment a dichroic second reflector surface is provided.

Abstract: Disclosed is a radiation collector apparatus and method primarily for counting and analyzing a flow of dilute particulate material, such as blood cells, sperm cells and the like, through the use of light detection. The radiation collector apparatus comprises a reflector chamber having an ellipsoidal reflector surface with a pair of elipsoidal foci defining a first focus, f11, and second focus, f12, and a second reflector surface with a primary focus, f21, positioned at the same point as focus f12, and a secondary focus, f22. The second reflector surface has the configuration of one of the conic sections of revolution. In operation the radiation collector apparatus is provided with an intensifed beam of light and a stream of particulate material aligned to intersect the intensifed beam of light at focus f11. Detectable light signals, after two reflections, are received in a focused beam by a photosensitive detector.
