摘要： Disclosed is a vapor axial deposition apparatus. The vapor axial deposition apparatus includes a first torch, a growth size detecting unit and a controlling unit. The first torch deposits soot on a distal end of a soot preform aligned with a first axis, and is aligned with a second axis. The growth size detecting unit detects an image including a growing point of the soot preform and an end of the first torch. The controlling unit calculates a distance between the soot preform and the first torch along the second axis from the detected image, and moves the soot preform upward based on the calculated distance.

摘要： Disclosed is a focusing device for a beam projector, which includes an adjustment member mounted on a housing of the beam projector to be linearly movable, a pivoting member rotatably mounted on the housing, a link member extending from the pivoting member at a point separated from a rotation axis of the pivoting member, and a lens assembly mounted to be linearly movable within the housing while interfering with the pivoting member, in which the link member rotates the pivoting member according to the linear movement of the adjustment member and the lens assembly linearly moves within the housing according to the rotation of the pivoting member. The focusing device can perform fine focusing and adjust the focusing distance without using a gear or motor to make the beam projector compact and mount the beam projector on the portable terminal.
