This Eschenbach Galilean telescope for distance is available in a binocular system. Galilean systems are small, lightweight optical systems that offer a bright image. They consist of a plus objective lens and a minus ocular lens.
Its unique adjustable frame allows the system to be fit immediately so it can be used THAT DAY! No lab required! The adjustable bars for the pupillary distance can be locked in place simply by tightening the screws and using the included lock washer. Finally, the frame features cold bend wire-core temples (150 mm in length) and an adjustable saddle bridge.
