Provided are a precision alignment device of an optical component and a method of using the device. The device includes a location fixing unit inserted and coupled to a pin hole on an optical table, closely attached to an optical mount, and fixes a location of the optical component, and a bumper including a penetration hole formed to allow the location fixing unit to penetrate to be coupled thereto, the bumper having a thickness formed in a lateral direction to maintain a certain distance between the location fixing unit and the optical mount when at least one side is closely attached to the optical mount. A location of the optical mount is determined while coupling the bumper to the location fixing unit.
