INVERSION TYPE MICROSCOPE WITH MANIPULATOR

摘要

PURPOSE:To improve operability and the operation efficiency of bricking by operating plural hydraulic operation parts associatively through a transmission tube and providing a lower-limit stopper for a needle holder to a hydraulic operation part other than a hydraulic operation part which is associated with a focusing mechanism. CONSTITUTION:A sample placed on a stage 12 is put in focus through a collimation handle 22. Then, a hydraulic operation part 23 is coupled with the fine adjusting handle 22a of the collimation handle 22. A glass needle 16 is set. The rough adjusting handle of a hydraulic drive part 17 and the fine adjusting knob of a hydraulic operation part 26 are used in combination to lower the needle holder 15 and the tip of the glass needle 16 is set slightly above the focus position. Then, the fine adjusting joy stick of the hydraulic operation part 26 is swung slowly to its lower-limit stopper position. Further, the fine adjusting knob is rotated in this state to lower the glass needle 16 until its tip reaches the focus position. Thus, the glass needle 16 is set at the lower-limit position of the tip part, and consequently the glass needle is not broken in bricking and the operation efficiency is improved.
