An alignment assembly includes a sensor and a lid that includes a first window. The alignment assembly also includes a rotary joint coupled to the lid. The alignment assembly also includes a jig coupled to the rotary joint and pivotable relative to the lid about the rotary joint. The jig includes an extendable arm that is moveable from a retracted position where the sensor is disposed in a first position above the first window to an extended position where the sensor is disposed at a second position above the first window. The alignment assembly also includes a lock configured to selectively pivotably lock the jig to the lid and also to selectively lock the extendable arm in the retracted position or the extended position.
