Abstract
In a lens module assembly method, a lens holder is placed in a receiver. The lens holder has a nest. A lens element is deposited in the lens holder. During the depositing, the lens element seats in the nest, if the lens element is in a forward-facing orientation. Entry of the lens element into the nest is interrupted, if the lens element is in a rearward-facing orientation.

1 more element
A lens module assembly method comprising the steps of:
- placing a lens holder in a receiver of a fixture, said lens holder having a nest having an opening, said fixture having an intrusion member extending outward from said receiver through said opening;
- depositing a lens element in said lens holder, said lens element having forward and rearward optical surfaces and a support portion, said rearward optical surface being concavely curved and defining a recess, said forward optical surface being less-recessed than said rearward surface;
- during said depositing, seating said lens element in said nest wherein said intrusion member extends into said recess and closely adjoins said rearward optical surface.
An assembly intermediate comprising:
- a fixture having a base, a receiver recessed in said base, and an interference member extending outward from said receiver, said receiver defining an optical axis, said interference member having a free end spaced outward from said receiver in a direction parallel to said optical axis;
- a lens holder closely held in said receiver, said lens holder having a nest aligned with said optical axis, said nest having a central opening and a rim disposed outward of said central opening in a direction parallel to said optical axis, said interference member extending through said opening into said nest, wherein said free end is disposed within said nest, interior to said rim.
