Pseudo-telecentric optical design of flow cytometric blood cell analysis dexterity

摘要

(57) Abstract The pseudo telecentric flow site metric optical system which detects several properties of the grain which floats in the media which flows simultaneously. As for this system, the grain the flow electrolysis cell (128) and the light (121) which are passed one receives optical system and the light which are sent to on the flow grain inside the flow electrolysis cell from the illuminant (120) from the flow grain each at almost one time, one among the detectors of the first deck or the lateral angular optical collection system (150) and the light which are sent to the multiple detectors receives from the flow grain, one among the detectors of the second deck or has with the front angular optical collection system (160) which is sent to the multiple detectors. The lateral angular optical collection system is produced including the condensing lens (132) which sends light to the detector of the first deck, the ejection pupil (151) of the condensing lens is laid out on the rear focal plane of the condensing lens, one inside the detector (141, 142, 143 and 144) of the first deck or the exposure to light surface of the multiple detectors, in order for the image of the ejection pupil to be registered on that exposure to light surface, is laid out in the conjugate dot of the rear focal plane of the condensing lens. As for the front angular optical collection system, it is possible to include the collection glass lens (130) which sends light to the detector (131) of the second deck the collection glass lens ejection pupil is laid out inside the rear focal plane of the collection glass lens, one among the detectors of the second deck or the exposure to light surface of the multiple detectors is laid out on the rear focal plane of the collection glass lens.
