Claim Text:
1. An optical testing device comprising: a base defining a sliding groove extending along a first direction in a top surface thereof; a holder sliding along a second direction on the top surface of the base; an interval regulator connected to the holder; and a plurality of illuminating modules slidably received in the sliding groove; wherein each of the illuminating modules comprises a circuit board and a single lighting element set on the circuit board, the interval regulator drives the holder to slide along a second direction so that a distance between the holder and the illuminating modules is regulated, and the first direction is not parallel to the second direction, wherein the sliding groove has a predetermined width along a direction perpendicular to a top surface of the base, and the illuminating module slides along the width direction of the sliding groove in a predetermined range; a height regulator set above the sliding groove along a direction perpendicular to the top surface of the base, wherein the height regulator comprises a driving pole telescopically extending along the width direction of the sliding groove, and a distal end of the height regulator is connected to the illuminating modules to regulate a height of the illuminating modules along the width direction of the sliding groove.
