|1. An optics device for use in an optical communications module for coupling light between an end of at least one optical
fiber and an optoelectronic device of the module, the optics device comprising:
a lens block, the lens block having a body, the body having at least a first optical surface formed therein and at least a
first alignment feature formed therein, the first alignment feature having a known spatial relationship with the first optical
surface such that positional and angular alignment of the first alignment feature relative to an optical axis of the lens
block guarantees positional and angular alignment of the first optical surface relative to the optical axis of the lens block.
