Optical device for cooperation focusing mechanism

摘要

Improving the focusing mechanism of the present invention relates multi-channel optical system. Optical apparatus for observing a An image is provided. The optical device comprises an optical two channels which are arranged adjacent to one another, each optical channel includes an image detector assembly and a complementary objective lens at a distance from each of the image detector. Focusing mechanism, which is directly or indirectly bound to the objective lens assembly or both of the image detector assembly of both the focus mechanism to adjust the distance each between the objective lens of the optical channel and the image detector and is configured to. The focusing mechanism includes a rotatable portion having a threaded two segments, each screw segment is not the same screw pitch. Therefore, it is possible by the rotation of the rotatable portion, and adjust a rate not identical, the respective distances between the objective lens of the optical channel and the image detector.
