Abstract
The invention relates to an adjustment mechanism for a secondary lens group of an astronomical telescope. The adjustment mechanism comprises a lens frame, an adjustment seat, pulling plates, a spring, a locking nut, a secondary reflector, a second lens and a first lens. The periphery of the adjustment seat is connected in a front sleeve ring through a plurality of pulling plates. The lens frame is a cylinder, and the rear end of the interior of the cylinder is provided with a cylindrical groove. The center of the front end of the cylinder is provided with a semi-circular projection, and the front end of the semi-circular projection is provided with an adjustment column. The center of the rear end of the adjustment seat is provided with a semi-circular groove, and the interior of the semi-circular groove is provided with a through hole. The adjustment column of the lens frame passes through the through hole of the adjustment seat, and the semi-circular projection of the lens frame is disposed in the semi-circular groove of the adjustment seat. The front end of the adjustment column is provided with the locking nut, and the spring sleeve is disposed outside the adjustment cylinder. Moreover, the rear end of the spring jacks the front end of the adjustment seat, and the front end of the spring jacks the rear end of the locking nut. The front end of the adjustment seat is provided with an outer cover, and the outer cover covers the locking nut, the spring and the adjustment column. The mechanism is ingenious in design, is compact in structure, is simple and convenient for adjustment, and is higher in stability.
Description
technical field [0001] The invention relates to the field of telescopes, in particular to an adjustment mechanism for a secondary mirror group of an astronomical telescope. Background technique [0002] At present, the adjustment mechanism of the secondary mirror group of the Schmidt-style reentrant astronomical telescope is designed with a correction plate, which is heavy and will cause chromatic aberration and aberration. The entire correction plate of the Schmidt telescope also makes the entire lens barrel in an airtight state, so that the constant temperature of the lens barrel is longer; the traditional Newtonian telescope can be pulled by a pull plate, but the optical axis of the entire system may be deflected due to the vibration generated during use, and the user does not So easy to debug. Moreover, the Newtonian telescope with the same aperture and focal length is longer than the telescope of this design, even more than twice as long, which makes it more cumbersome...
