S8984 has about 2 mega (1700 1200) p ixels each of which is 20 20 m. the fiber optic plate (fop) used as an input window is as thin as 1.5 mm but highly resistant to x-ray irr adiation, making S8984 very reliable even over a long-term operation. the scintillator coated on the fop is optimized to have high x-ray sensiti vity and high resolution (20 lp/mm). s8985-02 is an easy-to-use x-ray imaging module using S8984, with added functions such as a cable assembly and x-ray trigger ci rcuit. s8985- 02 is pin compatible with s8981-02 (number of pixels is increased). s8985-02 is advanced type of s8985 and adapted both ac and dc x-ray sources. 1 selection guide type no. cooling number of total pixels number of active pixels active area [mm (h) mm (v)] S8984 s8985-02 non-cooled 1708 1202 1700 1200 34 24 general ratings parameter S8984 s8985-02 ccd structure full frame transfer fill factor 100 % number of active pixels 1700 (h) 1200 (v) pixel size 20 (h) 20 (v) m active area 34 (h) 24 (v) mm vertical clock phase 2 phase horizontal clock phase 2 phase output circuit emitter follower without load resistance dimensional outline 39.5 (h) 27.5 (v) mm 42.6 (h) 30.6 (v) mm reliability 100,000 shots at 60 kvp, 30 m roentgen window scintillator on 1.5 mm fop other mpp mode (low dark current operation), module (s8985-02)
