ABSTRACT:
A method of registering a molded lenslet array (14) with an array of light emitting elements (54) includes etching an array of light source registration recesses (42) in a silicon pad (28). At least two registration recesses (30) are etched in the silicon pad. The registration recesses and the light source registration recesses have the same depth. Sidewalls of the registration recesses and the light source registration recesses have the same slope angle. A light emitting element is located in at least one of the light source registration recesses. The molded lenslet array is located at a predetermined distance from the bottom of the registration recesses (36). The molded lenslet array which is in a x-direction is located by matching a tapered locating surface of a first and second registration pin (72, 74) to a first and second tapered locating surface (68, 70) of a first and second registration recess (76, 78). The molded lenslet array is located in a y-direction by matching a first tapered locating surface (68) of a first registration pin (72) to a second tapered locating surface (70) of the first registration recess (76).
