| titleOfInvention | 2. 5mm spiral negative pole focus system of focus |
| abstract | The utility model provides a 2.5mm spiral negative pole focus system of focus, including focus cover and focusing electrode, there is the block platform focus cover bottom, cave in to square strong -focusing groove in the middle of the focus cover, there is waist circular shape weak focus groove the bottom surface in strong -focusing groove, the high H in strong -focusing groove is 13mm, the length F in weak focus groove is 10mm, width D is 3mm, the bottom surface in strong -focusing groove still is equipped with two screw holes, the focusing electrode top is equipped with the block groove, be equipped with two fastening holes of matcing with the screw hole in the middle of the focusing electrode, still be equipped with two negative pole mounting holes that run through in the middle of the focusing electrode, the assembly of focus cover is on the focusing electrode, cathode modulation silk installation back, its peak is 0.1mm for the high N of strong -focusing tank bottom face. Through focus cover structural design, the size of optimization strong -focusing and weak focus to the assembly structure of improvement and focusing electrode, realization focal spot size is 2.5mm, and convenient assembling stability is strong, the especially adapted industry field of detecting a flaw of being applied to. |
