Precise Optical Theodolite 1 Second

1″精密光学经纬仪

Geodetic control and precise alignment still use optical instruments where batteries and electronics are unwelcome. This 1″ theodolite reads by coincidence micrometer to 0.2″, with a 60 mm objective and 30× or 45× eyepieces. The 6″/2 mm plate level allows careful levelling for first-order direction sets.
