Abstract
The present invention discloses an optical testing device includes a base, a holder, and a number of illuminating modules. The base defines a sliding groove extending along a first direction in a top surface thereof. The holder slides along a second direction on the top surface of the base. The interval regulator is connected to the holder. The illuminating modules are slidably received in the sliding groove. 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. The first direction is not parallel to the second direction.
