Swarovski BTX Eyepiece
The BTX was a revolution in observation technology, and the results are dramatic. If you truly want to see it all, the BTX’s binocular capabilities make it unparalleled in both glassing efficiency and accuracy.
The BTX features an adjustable forehead rest, an angled ocular system, and the fact that both eyes can be used for viewing with maximum comfort over long periods
The BTX Modular uses the 95 mm, 85 mm, and 65 mm Objectives of the current SWAROVSKI OPTIK ATX/STX Modular system.
The 95 mm Objective Lens will be a fixed 35x, the 85 Objective Lens a fixed 30x, the 65 mm Objective Lens a fixed 30x.
Features SWAROVISION Technology Field Flattener and High Definition Lenses: Gives perfect edge-to-edge clarity, eliminates several kinds of distortion, brings out the highest color contrasts, and offers increased eye relief.
The interpupillary distance is adjustable, just like on a binocular. In the case of the BTX, the eyepieces operate simultaneously so they remain centered. No need to move away from the forehead rest while adjusting.
The black housing which incorporates the forehead rest can be removed for cleaning.
