1. An optical element assembly comprising:
- at least first and second optical elements, each of said optical elements having an optical axis and an optical surface portion with first and second mounting extensions extending away from the optical axis from the surface portions,first and second pins extending axially from the first and second mounting extensions, respectively, of the second optical element,first and second openings on the first and second mounting extensions of the first optical element, said openings positioned to receive the first and second pins, andmeans for preventing relative axial movement of the optical elements.

Abstract
An optical element assembly includes at least first and second optical elements. Each element has molded extensions to assist in the mounting. A pair of pins extend from the extensions on one element and fit into a pair of openings on the extensions of the other element. A clip having a hole in one leg to fit over the pin is positioned to urge each set of extensions together to prevent axial movement of one element with respect to the other.

2. An optical element assembly comprising:
-
at least first and second one-piece molded optical elements, each optical element having an optical surface portion defining an optical axis and first and second mounting extensions extending away from the optical axis, first and second pins extending axially from the first and second mounting extensions of the second optical element, first and second openings in the first and second mounting extensions, respectively, of the first optical element, the first opening being positioned and sized to receive snugly the first pin, the second opening being elongated away from the first opening and being sized to receive the second pin while snugly preventing movement of the first element around the first pin, the first and second extensions of one or both of the elements being extended axially to space the surface portions of the elements, and first and second clips fitting over the first and second mounting extensions of both optical elements, each clip having two resilient legs urging the extensions axially together and preventing relative axial movement between the first and second elements. - View Dependent Claims (3, 4)
