摘要： There is provided a calibration apparatus used for a photon counting type of radiation detector. In this apparatus, a radiation condition of a radiation is set such that particles of the radiation (X-rays) which are incident on a plurality of detection modules are piled up over each other at a probability which is equal to or less than a predetermined value. Under the setting of this radiation condition, detection sensitivities for the radiation are made uniform among the plurality of detection modules. Using this uniformed result, the detection sensitivities for the radiation are further made uniform every channel of each of the pixels formed by circuit groups including the plurality of detection modules, discrimination circuits and data calculation circuits and every discrimination circuit in each channel.

摘要： The invention relates to a small-format, low-cost zoom lens that can gain sufficient telecentricity and aberration performance even with the use of an inexpensive vitreous material, and so lends itself to an electronic image pickup device. The zoom lens comprises a first lens group G1 of negative refracting power, a second lens group G2 of positive refracting power and a third lens group G3 of positive refracting power. For zooming, the lens groups are moved with a change in the spacing between adjacent lens groups. The second lens group G2 comprises a first lens of positive refracting power, a second lens of positive refracting power and a third lens group of negative refracting power, and has three lenses in all. The third lens group G3 comprises a positive lens that is of meniscus shape convex toward an image plane of the zoom lens system and satisfies condition (3), n≦1.53.
