Abstract:
A portrait lens configuration for meeting handheld device form factor constraints. First and second meniscus lenses each have a reflective surface to provide internal reflections for transmitting light toward a focal plane. A third lens is positioned between the meniscus lenses and the focal plane. The first lens includes an anterior concave surface having a reflective material extending over a portion thereof. Light received by the first meniscus lens can be transmitted therethrough. The reflective material is positioned along the anterior concave surface to receive light transmitted therethrough and reflected back from the second lens. In an associated method the first meniscus lens is positioned to receive light through a first of two opposing refractive surfaces. After each lens provides an internal reflection, reflected light is transmitted through the second of the two opposing surfaces and then through a bore positioned within the second lens to the third lens.

Claim (Index 13):
A lens system comprising a first meniscus lens, a second meniscus lens and a third lens each positioned along a common optical axis to transmit light received from an object to a focal plane, the first lens including a concave transmissive first surface and a convex parabolic second surface having a first radius of curvature,\n the second lens including a concave parabolic first surface characterized by a second radius of curvature, complementary to the first radius of curvature of the second surface of the first lens, and a convex second surface, the second lens including a bore positioned along the optical axis wherein, when positioned between the object and the focal plane, to provide an image of the object along the focal plane: (i) the concave, transmissive first surface of the first lens faces the object to receive and refract light traveling from the object for entry into the lens system through the first lens for focusing along the focal plane, (ii) the concave parabolic first surface of the second lens is positioned to face the convex parabolic second surface of the first lens in spaced apart relation from the convex parabolic second surface of the first lens at a separation distance not exceeding 0.06 mm for all operative portions of the surfaces through which light passes before becoming focused along the image plane, (iii) light from the object which is transmitted through the concave parabolic first surface of the second lens is internally reflected along the second surface of the second lens; (iv) the light internally reflected along the second surface of the second lens is then internally reflected along the first surface of the first lens; and (v) the light internally reflected a second time enters the bore and is transmitted through the third lens to the focal plane.
