    摘要: A light guide lens (50) includes a front light-exit surface (51), a rear end surface (52) formed with a recess (55), and an outer surrounding surface (53). The front light-exit surface (51) is a convex surface disposed at an optical axis (Z). The rear end surface (52) includes a curved surface portion (521) that defines an innermost end of the recess (55), and that is a convex surface. The rear end surface (52) further includes an inner surrounding surface portion (522) that extends rearward from a periphery of the curved surface portion (521). The outer surrounding surface (53) diverges forwardly along the optical axis (Z), and includes a first curved surface part (531) and a second curved surface part (532) The first and second curved surface parts (531, 532) are disposed on opposite sides of an imaginary plane on which the optical axis (Z) is disposed, and are asymmetrical relative to each other with respect to the imaginary plane.

    摘要: An imaging lens (2) includes plastic-made first, second, third, fourth, and fifth lens elements (3, 4, 5, 6, 7) arranged in the given order from an object side to an imaging side, each having object-side and imaging-side surfaces (31, 41, 51, 61, 71; 32, 32, 52, 62, 72) facing toward the object and imaging sides, respectively. The first lens element (3) has a positive focusing power, and the object-side surface (31) thereof is a convex surface. The second lens element (4) has a negative focusing power, and the imaging-side surface (42) thereof is a concave surface. The third lens element (5) has a positive focusing power, and each of the object-side and imaging-side surfaces (51, 52) thereof is a convex surface. The fourth lens element (6) is a meniscus lens, and the imaging-side surface (62) thereof is a convex surface. The imaging-side surface (72) of the fifth lens element (7) has a concave area (721) in a vicinity of an optical axis (I) of the fifth lens element (7).
