A MICROSCOPE FINE FOCUS CONTROL MECHANISM |
摘要 |
A monoaxial adjusting system is provided for accomplishing both coarse and fine focusing adjustments between the nosepiece and stage of a microscope. The coarse adjustment is made by rotation of either of two coarse adjusting knobs which in turn directly rotates a coarse adjusting shaft and cam. Suitable linkage is connected to the cam to affect linear movement between the nosepiece and stage. Fine adjustment is made through rotation of either of two fine adjusting knobs which actuate the coarse shaft and cam through a planetary gear reduction system and follower. A further adjusting mechanism is lever operated so that the operator may easily provide fine adjustment while manipulating the North-South stage and East-West slide control knobs. The entire adjusting system is spring and gravity loaded to eliminate backlash. |
