Adapter ring is used between camera(or projector) and lenses,it could mount kinds of conversion lenses,such as telephot lens,wide angle lens,fisheye lens,and so on.Adapter rings are labeled from the camera to the filter. For example, a 25.5mm to 46mm step up ring is used for a camera (or lens) with 25.5mm threads. The adapter will allow a 46mm filter (or other adapter ring) to fit. Adapter rings can be stacked. To use a 49mm filter on a 25.5mm camera lens, first use a 25.5mm to 46mm step up ring and then a 46mm to 49mm step up ring.Specification of our adapter ring as follow: *M25,27,28,30,30.5,34,40.5mm,43mm,46mm,49mm to 37mm *M37,40.5,43,49,55,58,62 to 52mm *M52,55 to 58mm *M55,58,62,67 to 72mm *M67,72,77 to 82mm

Cylindrical lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either plano concave or plano co
Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.Sp
Telephoto lens has a narrower angle of view,it thus gives apparent magnification to objects,it also seems to compress distant things, and there is less depth of field. The most obvious is to allow pho
