波測距儀の光量調整用フィルター。A rotatable density variable filter provided in the light receiving optical path that divides the optical path incident on the light receiving element into two and guides the ranging light to one side and the reference light to the other, and the reference light and the ranging light are guided respectively. In a filter for adjusting the light amount of a light wave rangefinder configured to transmit through the first ring and the second ring of the filter, the annular zone between the first ring and the second ring, the inside of the first ring, and the second ring 1. A light amount adjustment filter for a light wave range finder, characterized in that the outside of the filter is made opaque, facilitates position adjustment when installing the filter, and prevents distance measuring light and reference light from mixing with each other.
