Abstract
The utility model provides a multiple-variable eyepiece with a diaphragm. The multiple-variable eyepiece comprises an outer cylinder. A hand wheel is arranged on the outer surface of the outer cylinder. A first guide groove and a second guide groove are arranged on an outer cylinder wall. An inner cylinder is sleeved on the inner side of the outer cylinder. A third guide groove, a fourth guide groove and a fifth guide groove are arranged on an inner cylinder wall. An eyepiece body is fixed in the inner cylinder and is connected with a compensating mirror and a multiple-variation mirror respectively through a first guide nail and a third guide nail. The outer ends of the first guide rail and the third guide rail respectively penetrate through the third guide groove and the fifth guide groove of the inner cylinder to be disposed in the first guide groove and the second guide groove of the outer cylinder. The multiple-variable eyepiece is characterized in that the inner cylinder is positioned between the multiple-variation mirror and the compensating mirror and is connected with the diaphragm through a second guide nail, and the outer end of the second guide nail penetrates through the fourth guide groove of the inner cylinder to be disposed in the second guide groove on the outer cylinder wall. The outer cylinder is enabled to rotate reversely during rotation of the inner cylinder to drive the compensating mirror, the multiple-variation mirror and the diaphragm to move simultaneously to realize multiple variation and focusing, and through synchronous movement of the diaphragm, blurred and fussy viewing field edges are effectively avoided.
Description
Technical field
The utility model relates to a kind of telescope with becoming times eyepiece, and particularly a kind of change times eyepiece with the light hurdle belongs to Optical Instrument Designing and manufacturing technology field.
Background technology
In known telescope, the eyepiece that has has anamorphosis function, when the eyepiece that adopts this change doubly to design, can play the effect of the whole enlargement factor of conversion telescope, because it is comparatively special to become the optical system of times eyepiece, most of eyepiece does not have special light hurdle, like this when observing object, the visual field surrounding edge is virtualization and fuzzy, brings visual discomfort to the observer.In addition, fuzzy field of view edge also can influence normal observation, but also impacts for the accuracy of observation.Therefore be necessary prior art is improved.
Summary of the invention
For solving the existing times eyepiece that becomes because not establishing the light hurdle, make the fuzzy virtualization of observation field of view edge, thereby influence the problem of normal observation, the utility model provides a kind of change times eyepiece with the light hurdle, so that when being installed on the telescope, can effectively avoid virtualization, fuzzy field of view edge.
The utility model is finished by following technical proposal: a kind of change times eyepiece with the light hurdle, comprise urceolus, the appearance of this urceolus is worn handwheel, establish first on the outer tube wall, second guide groove, the urceolus inboard is socketed with inner core, this inner tube wall is provided with the 3rd, the 4th, the 5th guide groove, and eyepiece is arranged fixedly in the inner core, and respectively by first, the 3rd guide pin is connected with compensating glass and becomes times mirror, and first, the the 3rd and the 5th guide groove that the outer end of the 3rd guide pin is passed inner core respectively places first of urceolus, in second guide groove, it is characterized in that becoming between times mirror and the compensating glass in the inner core, be connected with the light hurdle by second guide pin, the 4th guide groove that inner core is passed in the second guide pin outer end places second guide groove on the outer tube wall, when by handwheel rotation inner core, the counter-rotating of drive urceolus, make the 3rd of inner core, the 4th, the 5th guide groove is in rotation process, promote first by the guide groove wall, second, the 3rd guide pin is along first of urceolus, second guide groove moves, thereby drive corresponding compensating glass, become times mirror, the light hurdle moves, realize focusing, effectively avoid virtualization simultaneously, fuzzy field of view edge.
Described smooth hurdle one side is the cylinder of band opening end, and opposite side is uncovered small bore end, and the opening end of cylinder is enclosed within on the picture frame that becomes times mirror.
First guide groove on the described urceolus, second guide groove are straight-line groove.
The the 3rd, the 4th, the 5th guide groove on the described inner tube wall is made as helicla flute.
The utlity model has following advantage and effect: adopt such scheme, can when the rotation inner core, make the rotation of urceolus synchronous backward easily, so that in rotary course, drive compensating glass, change times mirror, light hurdle move simultaneously, realize zoom and focusing, and pass through the same moved further on light hurdle, effectively avoid virtualization, fuzzy field of view edge, make telescope can be clear, accurately, normally observe, when improving observing effect, also allow observer's visual experience more comfortable.Be a desirable change times eyepiece in fact.
