OBBT-100 This is a modified version of the 25/40x100mm, but with 1.25'' non-rotating helical focusers instead of permanently-mounted eyepieces on rotating turrets. A matched pair of 25x (24.43mm) fully multi-coated wide-angle eyepieces are included.. And because the helical focusers are a non-proprietary 1.25'' design, your favorite 1.25'' eyepieces can be used as well. The eyepieces do not rotate when focusing- a feature found only on high-end helical focusers. The rest of the binocular, including the semi-apochromatic triplet objectives, is the same proven design as found in the original 25/40x100mm. And just like the 25/40x100mm, broadband multi-coatings (non-reflective green/purple) are used throughout, including on the massive porro prisms. Features: -Objective size: 100mm (f/l 620mm). -Magnification: 25x included, accepts any 1.25'' eyepieces. -Prism: BAK4. -Optic coating: Fully Multi-coated including all oculars. -Field of view: 25x- 2.5 ; Apparent FOV- 67 . -Exit pupil diameter: 25x- 4mm. -Exit pupil distance: 25x- 16mm. -IPD (inter-pupil distance) range: 58-80mm.
