1. A device, comprising:
a nozzle configured for vacuum-lifting a lens element, the lens element comprising a landing surface suction-lifted by the nozzle, a bonding surface opposite to the landing surface, and an receiving surface substantially perpendicularly connecting the bonding surface and the landing surface, the lens element defining a substantially rectangular recess in the bonding surface and comprising a first lens bulging up from a bottom surface of the recess and a second lens bulging up from the receiving surface, the lens element also defining a triangular groove in the landing surface which optically couple the first lens with the second lens; a driver configured for driving the nozzle to position the lens element onto a substrate, the substrate supporting and electrically connected with a light receiver, the substrate being configured to drive the light receiver to receive a laser beam; and a light emitter comprising a holding rod and configured for emitting the laser beam; wherein the driver comprises a connecting surface, the nozzle and the holding rod both extend from the connecting surface along the substantially same direction, a sum of a height of the nozzle and a distance from an optical axis of the second lens to the holding surface is substantially equal to a distance from an optical axis of the light emitter to the connecting surface, when the lens element is suction-lifted by the nozzle, and the driver is configured to adjust a position of the lens element on the substrate until the power of the laser beam measured by the light receiver reaches a maximum value. |
