摘要： A sight includes a main body, an erecting unit, and a first adjusting element. The erecting unit includes a second magnetically attractable element and movably disposed within the main body. The first adjusting element includes a first magnetically attractable element and is movably disposed on the main body. The first adjusting element extends into the main body and against the erecting unit. The first magnetically attractable element attracts the second magnetically attractable element so that the first adjusting element contacts the erecting unit. The first adjusting element is rotatable to move the erecting unit in a first direction.

摘要： A lens assembly comprises sequentially from an object side to an image side along an optical axis a first lens, a second lens, a third lens, a stop, a fourth lens, a fifth lens and a sixth lens. The first lens is a meniscus with refractive power and includes a convex surface facing an object side and a concave surface facing an image side. The second lens is with negative refractive power and includes a concave surface facing the object side. The third lens is with positive refractive power and includes a convex surface facing the image side. The fourth lens is with positive refractive power and includes a convex surface facing the image side. The fifth lens is a biconcave lens with negative refractive power. The sixth lens is with positive refractive power and includes a convex surface facing the object side.

摘要： A bi-reticle sight includes a main body, a first reticle, a second reticle and a sensor. The first reticle is configured to move along with the main body. The second reticle is configured to move relative to the first reticle. The sensor is configured to detect the main body to determine whether the main body is in a standard attitude. Wherein the first reticle coincides with the second reticle when the main body is in the standard attitude, the second reticle is moved relative to the first reticle to a position corresponding to the standard attitude when the main body is not in the standard attitude.

摘要： An ocular structure for observation apparatus includes a first member, a second member and a main body. The first member includes at least one slot and a plurality of first limiting mechanisms. The second member includes at least one slider extending into the slot and a plurality of second limiting mechanisms. The main body includes an ocular lens unit, wherein the first member and the second member are mounted on the main body. The slider is moved in the slot when the first member and the second member are in relative rotation, and the first limiting mechanisms directly or indirectly match the second limiting mechanisms to position the first member with respect to the second member.

摘要： A magnification apparatus includes a main body, an inner sleeve, an outer sleeve, an adjusting ring and a locating element. The inner sleeve is disposed within the main body. The outer sleeve includes a locating hole, wherein the outer sleeve is rotatably disposed around the inner sleeve. The adjusting ring is rotatably disposed around the main body to rotate the outer sleeve relative to the main body and the inner sleeve. The locating element includes a fixing element, an elastic element and a locating sleeve, wherein the locating sleeve is placed to penetrate through the main body and the locating hole and against an outer surface of the inner sleeve, the fixing element is disposed on the adjusting ring, and the elastic element includes a first end placed against the fixing element and a second end placed against an interior of the locating sleeve.
