Measuring device has collimation optical unit having wide viewing angle formed on main housing to collimate output of telescope optical unit

摘要

A telescope optical unit collimates an observation point to form an image on an image sensor. A collimation optical unit having wide viewing angle, formed on the main housing, collimates the output of the telescope optical unit. An automatic collimation mechanism adjusts the position of the observation point along the visual field, based on the positional information of the image.
