Embodiment Construction

[0015] In the following, the specific implementation manner of the present invention will be further described by taking an ultra-wide-angle short-focus optical system as an example in conjunction with the accompanying drawings.

[0016] The optical field of view of the ultra-wide-angle short-focus optical system is 87.5°, and the focal length is 3.47mm. figure 1 It is the mechanical assembly diagram of the ultra-wide-angle telephoto system. According to its own design characteristics: the two ends are larger in size and the middle is smaller. Its mechanical structure is divided into front group unit 2 and rear group unit 3. Figure 2(a) is an assembly diagram of the optical system of the ultra-wide-angle short-focus optical system, which is divided into 7 groups with a total of 9 lenses. According to the specification, a series of mechanical designs are being carried out for the ultra-wide-angle short-focus optical system to ensure its reliable operation in the space environme...

Abstract

The invention discloses a super-wide angle telescope suitable for the space environment. The telescope structurally comprises a front lens, a front set of lens unit and a rear set of lens unit. The super-wide angle telescope is structurally characterized in that 1, an installing plane is axially designed on a lens frame of the front lens, and an invar steel lining is radially embedded into the lens frame of the front lens; 2, multiple exhaust holes with the caliber being 1 mm are designed in relatively closed space of the front set of lens unit and the rear set of lens unit; 3, an adjusting heat insulating lining made of epoxy resin is additionally arranged between the two sets of lens units of an optical system; 4, a conical surface adjusting spacer is adopted in the rear set of lens unit. The super-wide angle telescope has the advantages that the telescope structure can reliably and stably work in the space environment with profound hypothermia, high vacuum and intense impact vibration, the manufacturing cost is low, and the assembly efficiency is high.

Description

technical field [0001] The invention relates to optical-mechanical design technology, in particular to a special design of an ultra-wide-angle telescope structure suitable for space environments. Background technique [0002] At present, optical systems have been widely used in civil, industrial inspection, national defense, aerospace and other fields. The tolerance allocation and mechanical structure design of optical systems have a great impact on system performance. Since the optical system is assembled under normal temperature and pressure, conventional means cannot guarantee the reliable operation of the optical system in the space environment. In order to ensure that the ultra-wide-angle telescope system can work reliably in the space environment, this paper proposes a unique mechanical design method, which not only ensures the assembly accuracy of the system, but also ensures Accuracy requirements and reliability in vibration and other environments, with the advantag...
