Abstract:
1. An apparatus for assembling a lens of an optical component having at least one optical fiber, a fiber block for fixing the optical fiber in position, and a cylindrical lens to be fixed to the fiber block with its optical axis aligned with that of the optical fiber, wherein the cylindrical lens is fixed, the apparatus comprising: a fiber block device to fix in position the fiber block on which the optical fiber is provided; a lens grasping device to grasp an outer peripheral side surface of the cylindrical lens supplied to a lens supply position; an adhesive applying device to apply an adhesive to one end surface of the cylindrical lens; a lens moving device to move the cylindrical lens grasped by the cylindrical lens grasping device to the adhesive applying device, and to place one end surface of the cylindrical lens, to which the adhesive has been applied, at a predetermined position of the fiber block; a light source to emit light to the optical fiber; a beam splitter to divide the light passed through the optical fiber and the cylindrical lens between a first direction and a second direction; a reflection mirror to cause a reflected light obtained through reflection of the light of the first direction, passing through the beam splitter, to enter the cylindrical lens again; an optical axis position measuring device to measure a optical axis and position of the light of the second direction; and an optical power meter to measure the output of the reflected light entering into the cylindrical lens again.
