Filed:

May 17, 2005

Appl. No.:

11/130714

Inventors:

Russell Lederman - Berlin MD, US
Clamore Dankmeyer - Berlin MD, US

International Classification:

G02B023/00

US Classification:

359399000, 359406000

Abstract:

A magnification changing system for a telescope, comprising a housing having a lightpath therethrough, which lightpath is adapted to be positioned in alignment with the lightpath of the telescope. The housing includes a movable portion for selectively positioning into and out of the lightpath of the housing at least one optical element. Movement of the movable portion selectively places the optical element into and out of a position coincident with the lightpath of the telescope, thereby selectively changing the effective focal length, and hence the magnification, of the telescope. In a preferred embodiment, the housing comprises a star diagonal, having the movable portion integrated on the telescope side of the housing, eyepiece side of the housing, or both sides of the housing.

Abstract:

An optical corrector system optical system comprising two components, a first housing supporting therein a telenegative-type lens, and a second housing supporting therein a positive-type lens. The first housing is adapted to be coupled to a telescope in a manner so that the telenegative lens intercepts the image plane provided by the telescope. The second housing is adapted to be coupled to an image input portion of a remote viewing device. Opposite ends of the first and second housings are adapted to be coupled to each other in a manner so that the distance between the telenegative lens in the first housing and the positive lens in the second housing results in the intercepted image plane being repositioned from a viewing position at the telescope, to a viewing position at the remote viewing device. In a preferred embodiment, the remote viewing device comprises a binocular viewer.
