Optical system with plano convex lens

1. An optical system, comprising:

a lens holder including mounting features to position a plurality of lenses, the mounting features including:

mounting features to position a first plastic lens proximate an aperture end portion of the lens holder;

mounting features to position a glass plano-convex lens having a substantially planar surface along an optical path through an interior of the lens holder; and,

mounting features to position a second plastic lens between the first plastic lens and the glass plano-convex lens.

2. The system of claim 1 , wherein the lens holder further comprises the second plastic lens positioned in the mounting features to position the second plastic lens.

3. The system of claim 1 , wherein the mounting features to position the glass plano-convex lens comprise mounting features to position a stage having the glass plano-convex lens mounted thereon.

4. The system of claim 1 , wherein the lens holder further comprises the first plastic lens engaged in the mounting features to position the first plastic lens.

5. The system of claim 1 , further comprising an imager positioned proximate an imaging end of the lens holder opposite the aperture end portion.

6. The system of claim 5 , wherein the imager is positioned in mounting features of the lens holder.

7. The system of claim 5 , wherein the lens holder further comprises:

a third plastic lens engaged in mounting features and positioned between the plano-convex lens and the imager.

8. The system of claim 1 , wherein the optical system comprises a miniature camera, and wherein the lens holder further comprises:

a third plastic lens positioned in mounting features to receive light from the glass plano-convex lens; and,

an imager configured to receive light from the third plastic lens and further configured to generate imaging information indicative thereof.

9. The system of claim 1 , wherein the optical system includes a miniature camera including the lens holder.

10. The system of claim 9 , wherein the optical system further includes a mobile electronic device including the miniature camera.

11. The system of claim 1 , wherein the mounting features are configured to position the glass plano-convex lens with the substantially planar surface of the glass plano-convex lens positioned toward the aperture end portion of the lens holder.

12. A mobile electronic device, comprising:

a miniature camera having a light receiving end portion and an imaging end portion, the miniature camera comprising:

a first plastic lens positioned at the light receiving end portion of the miniature camera;

a glass plano-convex lens positioned between the first plastic lens and the imaging end portion of the miniature camera;

a second plastic lens positioned between the first plastic lens and the glass plano-convex lens;

an imager positioned proximate the imaging end portion of the miniature camera; and,

a third plastic lens positioned between the glass plano-convex lens and the imager.

13. The device of claim 12 , wherein the glass plano-convex lens and the first plastic lens are included in a plurality of lenses, and wherein at least one lens of the plurality of lenses is positioned on a moveable stage.

14. The device of claim 13 , wherein the moveable stage is in communication with an actuator configured to apply force to the moveable stage, and wherein the actuator is in communication with a controller configured to generate an excitation waveform indicative of a desired position of the at least one lens.

15. The device of claim 12 , wherein the miniature camera further includes a shutter system.

16. The device of claim 12 , wherein the miniature camera is configured to provide at least one function selected from the group consisting of auto-focus, zoom, and image stabilization.

17. The device of claim 12 , further comprising at least one from the group consisting of a mobile security device, a cell phone, a mobile computing device, and a personal digital assistant.
