Description

A kind of digital vedio recording telescope with adjustable focus

One, technical field: the utility model belongs to a kind of digital vedio recording telescope with adjustable focus that relates in the optical instrument technical field.

Two, technical background: utilize telescope to watch scenery at a distance, it is the thing that people know already, yet it is irrealizable only utilizing telescope that scenery is at a distance noted, progress and development along with science and technology, particularly along with taking pictures and the development of camera technique, in order to observe scenery at a distance can note the desired scenery that obtains again simultaneously, scientists is designed the telescope with digital camera function.With the most approaching prior art of the utility model be a kind of Allring of being called digital telescope of finding from network (network address: http:www.pconline.com.cn) as shown in Figure 1, by binoculars and install additional thereon one need not (energy) focusing the imaging moiety of dolly-out,ing dolly-back form.The optical system structure of two lens barrels is the same about binoculars, and the telescopic ocular that is left lens barrel can be focused, and the telescopic ocular of right lens-barrel can not be focused.For convenience's sake, the corresponding identical piece number of two lens barrels adopts same Reference numeral about.Binoculars comprise: left and right sides telephotolens group 1, left and right sides benhain prism 2, the right telescopic ocular group 3 that can not focus, telescope focus adjusting mechanism 7, focusing wheel 8, the left telescopic ocular group 9 of adjustable focus, left and right sides lens barrel 10; The imaging that can not focus partly comprises: the telphotolens group 4 that can not focus, optical filter 5, COMS imageing sensor 6.The imaging moiety that can not focus is installed at about binoculars between two lens barrels, in order to draw and to indicate that Reference numeral is convenient, again can be possible from the structural principle, and we move to this part on the right side of right lens-barrel.

The subject matter that this device exists is: because the imaging moiety of dolly-out,ing dolly-back that can not focus can not be focused, the distant place scenery that it absorbs actual distant place object view state of seeing often and in binoculars is different, and the picture of picked-up is difficult to obtain the effect of projecting motif.

Three, summary of the invention: in order to overcome the shortcoming that prior art exists, the purpose of this utility model is, the distant place scenery state effect convergence that distant place scenery state effect that digital vedio recording obtains and actual observation in telescope are arrived is consistent, with outstanding needed theme, a kind of digital vedio recording telescope of ad hoc meter with adjustable focus.

The technical problems to be solved in the utility model is: a kind of digital vedio recording telescope with adjustable focus is provided.The technical scheme of technical solution problem: as shown in Figure 2, comprise binoculars and install the digital vedio recording part of an adjustable focus thereon additional.For convenience's sake, the corresponding piece number of two lens barrels adopts same Reference numeral in the binoculars.Binoculars comprise: left and right sides telephotolens group 11, left and right sides benhain prism 12, left graticule 13, the left and right sides is adjustable telescopic ocular group 14, telescope focus adjusting mechanism 19, focusing wheel 20, left and right sides lens barrel (21); The digital vedio recording of adjustable focus partly comprises: preceding object lens (15), back object lens (16), optical filter (17), the COMS imageing sensor (18) of looking in the distance of dolly-out,ing dolly-back of looking in the distance of dolly-out,ing dolly-back of adjustable focus.

In binoculars, about the optical axis of two lens barrels parallel, about two telephotolens groups 11 by self cylindrical shell, in the upper end of left and right sides lens barrel 21 is inserted into left and right sides lens barrel 21, be slidingly matched between the two, telephotolens group 11 can move up and down along optical axis direction in lens barrel 21; Left and right sides benhain prism 12 is contained in one side of close telescopic ocular group 14 in the left and right sides lens barrel 21, and left and right sides telescopic ocular group 14 is contained in the lower end of left and right sides lens barrel 21, is threaded engagement between the two, rotates telescopic ocular group 14, and it is moved up and down along optical axis direction; Regulate the distance of telescopic ocular group 14 and graticule 13, in left lens barrel 21, the vertical graticule 13 that is equipped with between benhain prism 12 and telescopic ocular group 14 with optical axis; Telephotolens group 11 moves up and down along optical axis, makes Scenery Imaging at a distance on graticule 13, about focus adjusting mechanism 19 is positioned in the middle of two lens barrels 21, with about two lens barrels 21 be connected, focusing wheel 20 is connected with the axle coaxial cable of focus adjusting mechanism 19; The digital vedio recording of adjustable focus partly be contained in binoculars about between two lens barrels 21, be positioned at the top of focus adjusting mechanism 19, the optical system components of digital vedio recording part, the order that is arranged in order along optical axis is object lens 16 after dolly-out,ing dolly-back of object lens 15 before dolly-out,ing dolly-back of adjustable focus looked in the distance, adjustable focus looked in the distance, optical filter 17, COMS imageing sensor 18 from top to bottom, wherein dolly-out, dolly-back look in the distance before the look in the distance lower end and the focus adjusting mechanism 19 of the telphotolens that back object lens 16 are constituted of object lens 15 and dolly-out,ing dolly-back be connected, upper end and left and right sides lens barrel 21 are connected; Optical filter 17 and COMS imageing sensor 18 is connected with fuselage in the middle of binoculars two lens barrels, the optical axis of the digital vedio recording part of adjustable focus with about the optical axis of two lens barrels 21 parallel.

Principle of work explanation: about benhain prism in two lens barrels can make the inverted image of seeing at telescopic ocular that transmits from telephotolens become upright real image, rotate focusing wheel 20, driving the telphotolens of the adjustable focus that is made of the objective lens before dolly-out,ing dolly-back and the back object lens 16 of dolly-out,ing dolly-back and left and right sides lens barrel 21 simultaneously by focus adjusting mechanism 19 moves up and down simultaneously along optical axis direction, this makes the focal plane of left lens barrel 21 telephotolens groups 11 drop on the graticule 13, the focal plane of the telphotolens of adjustable focus is also dropped on the image planes of COMS imageing sensor simultaneously, regulating left telescopic ocular 14 more also drops on the graticule 13 its focal plane, regulating right telescopic ocular group 14 makes its right eye adapt to observation scenery requirement at a distance, again because the optical axis of the telphotolens of adjustable focus is parallel with the optical axis of left and right sides lens barrel 21 and focusing simultaneously, like this, the digital vedio recording of observing the distant place scenery state see and adjustable focus by the binoculars distant place scenery state that partly absorbs record just reaches unanimity to greatest extent.

Good effect of the present utility model: the distant place scenery state that the digital vedio recording of adjustable focus is partly absorbed, most possibly with the distant place scenery state consistency of watching, thereby can satisfy the shooting demand that people want projecting motif in binoculars.

Four, description of drawings: Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present utility model.

Five, embodiment: the utility model is implemented by structure shown in Figure 2, the multiplying power of binoculars adopts 10 times, the bore of left and right sides telephotolens group 11 adopts φ 25mm, the form of plate 13 adopts form or the diagonal line square opening form that goes up following tangent line circle respectively, it is 10 times that the number newspaper picture telphotolens partly of adjustable focus adopts enlargement ratio, bore is φ 17mm, and the wave band of optical filter 17 and COMS imageing sensor are complementary.
