REFLECTION CONTROL APPARATUS USING PLANAR REFLECTIVE MIRROR HAVING PRISM CONSTANT OF ZERO

摘要

PURPOSE: A reflection control apparatus using a planar reflective mirror having a prism constant of zero is provided to measure accurately a mechanical constant or a prism constant of electro-optical distance meter by installing the planar reflective mirror on a side passing a center of a sphere of a spheric housing. CONSTITUTION: A planar reflective mirror(220) is vertically installed in the inside of a spheric housing(100). An inserting portion(120) is formed in the inside of the housing(100). The housing(100) is formed with a resin material or a metallic material such as aluminum or stainless steel. The planar reflective mirror(220) is vertically installed in the inserting portion(120). A cover(240) is used for contacting closely the planar reflective mirror(220) with the inside of the housing(100). A lower end portion of the housing(100) is combined with an upper portion of a tripod(300). A plurality of support bars(320) are formed on a lower portion of the tripod(300). A circular rotation body(420) is formed on an outer circumference of the tripod(300). A plurality of fixing screw portions(440) are inserted into one side of a position fixing plate(460). The fixing screw portion(440) is formed with a micrometer screw(470) and a position fixing screw(480).
