SV215 1.25 inch 3mm-8mm zoom eyepiece is the first zoom eyepiece launched by SVBONY brand for planetary eyepiece application. This zoom eyepiece adopts 4 groups of 6-piece optical structure (a kind of eyepiece containing high-quality heavy lanthanum flint glass), which is exquisite in design and less than 200g in overall weight. It is very convenient to carry out. The contact surface of each piece of glass is coated with full broadband antireflection coating, and the edge of the lens is subject to extinction and blackening treatment to ensure adequate imaging contrast.
In the zoom process of traditional zoom eyepiece, the field of view and pupil exit distance will change with the change of focus. Similarly, with the change of focal length, the telescope system will also lose focus obviously, because generally zoom eyepieces are not in focus design (all focal lengths cannot focus on the same point). The SV215 zoom eyepiece, with its precise structure and unique zoom mode, can keep the field of view and pupil exit distance constant during the zoom process without refocusing.
