    摘要： A scope includes an objective lens system having refractive power, a relay lens system having refractive power, and an eyepiece system having refractive power. The relay lens system includes a first, a second, and a third lens groups. The second lens group includes a II-2-1 lens and a II-2-2 lens, and both of which are cemented. The third lens group includes a II-3-1 lens having a convex surface facing an object side and a II-3-2 lens having a convex surface facing an image side, and both of which are cemented. The second lens group and the third lens group can move along an optical axis to change a magnification of the relay lens system and thereby change a magnification of the scope. The objective lens system, the relay lens system, and the eyepiece system are arranged in order from the object side to the image side along the optical axis.

    摘要： A lens device includes at least one frame, at least one lens, at least one optical element and an image forming assembly. The lens is disposed in the frame and has an optical axis extending in a first direction. The optical element includes at least one non-planar surface. The light coming from an object side propagates through the lens and the non-planar surface to the image forming assembly. The lens is obtained from cutting an upper portion and a lower portion of a circular lens along planes in parallel to the first direction and a second direction.

    摘要： The disclosure provides a collimating lens, a projecting module, and a mobile phone. An object side of the collimating lens is defined as adjacent to a laser transmitter, an image side of the collimating lens is defined as adjacent to an object to be measured. Along an optical axis from the object side to the image side, the collimating lens sequentially includes a first lens, a second lens, a third lens and a stop. An object side surface of the first lens is convex, an object side surface of the second lens is concave surface, an object side surface of the third lens is convex, and an image side surface of the third lens is convex. The stop is positioned between the third lens and the object to be measured. The material of each of the first lens, the second lens, and the third lens is plastic.
