摘要： An optical imaging lens includes six lens elements positioned sequentially from an object side to an image side along an optical axis. The image-side surface of the first lens element has a concave portion in a vicinity of the periphery of the first lens element and the object-side surface of the sixth lens element has a convex portion in a vicinity of the periphery of the sixth lens element. Gaa is a sum of all five air gaps from the first lens element to the sixth lens element along the optical axis, T5 is a central thickness of the fifth lens element along the optical axis, and Gaa and T5 satisfy the equation Gaa/T5≤3.85.

摘要： An ocular optical system configured to allow imaging rays from a display image to enter an observer's eye through the ocular optical system so as to form an image is provided. A direction toward the eye is an eye side, and a direction toward the display image is a display side. The ocular optical system sequentially includes a first and a second lens elements having refracting power from the eye side to the display side along an optical axis. Each lens element includes an eye-side surface and a display-side surface. An optical axis region of the eye-side surface of the first lens element is concave. An optical axis region of the eye-side surface of the second lens element is concave.

摘要： An optical imaging lens includes a first lens element, a second lens element, a third lens element, and a fourth lens element from an object side to an image side in order along an optical axis. The first lens element to the fourth lens element each include an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through. The object-side surface of the second lens element has a concave portion in a vicinity of the optical axis. The image-side surface of the second lens element has a convex portion in a vicinity of a periphery of the second lens element. The object-side surface of the third lens element has a concave portion in a vicinity of a periphery of the third lens element. The fourth lens element has negative refracting power.
