Abstract

The utility model relates to an ultraviolet-infrared multi-functional photographing device, comprising a lens, a bellow, an image intensifier, a pickup camera and a camera. The front of the camera is connected with one end of the bellow; the other end thereof is connected with the lens. The joint of the camera and the bellow is vertically connected with the image intensifier, the other end the image intensifier is connected with the pickup camera; the joint of the camera and the bellow is connected with a switching box, inside which a fixed wide spectrum beam divider that form a 45-degree angle with a camera light path and a light path of the image intensifier, is arranged. By adopting the fixed wide spectrum beam divider which is fixed in the switching box with 45-degree angle, the utility model does not need any movable parts to switch, thus reducing the operational programs and avoiding shake and displacement; therefore, the whole set of the device has the advantages of small volume, light weight and short light path. Since an optical filter is positioned at the rear of the lens, the diameter of the optical filter can be greatly shortened, which improves the quality of the optical filter and the sensitivity of the whole device.

Description

UV-Infrared multi-purpose picturing device

Technical field

The utility model relates to a kind of needs and carries out ultraviolet-infrared, extraordinary photographic means that low-light is for shooting.Be mainly used in criminal investigation work.

Background technology

Because the people is invisible to the naked eye or does not see ultraviolet light, faint light; Can only carry out blind bat by rule of thumb when taking under this light, success ratio is low, and is very inconvenient.Behind the image intensifier that full spectrum occurred, can be on the video screen of image intensifier with sightless photoimaging, but because the resolution of screen picture is not high, contrast is little, noise is strong, and it is undesirable, worthless causing the photographic quality of taking again by fluoroscopic image.

In order to obtain the photo of optimum efficiency, adopted slide plate between camera and image intensifier, to switch at present.Realized observing with focusing, carrying out the take pictures purpose of photograph of film with camera with image intensifier.Its weak point is that slide plate is a moving component, can cause that when sliding vibrations, displacement, location are forbidden etc., causes the photo effect of taking undesirable, and because this device volume is big, Heavy Weight, very inconvenience when hand-held search, observation.In addition, also adopted and between camera lens, camera, image intensifier, added a switching device shifter, this switching device shifter is mounted in it the catoptron of plating total reflection film angle at 45, lifts or removes by the level of catoptron, the conversion between observing, taking a picture.Its weak point be catoptron when level is lifted or is removed, can cause equally vibrations, the displacement.Lifting or removing owing to catoptron, all need big space, therefore this switching device shifter certainly will strengthen light path, having produced can only close-perspective recording, the problem of can not Reconnaissance, Long Range, observing, taking pictures, again owing to be manually to control catoptron, inevitably cause the light path of camera not open or open incomplete, take a picture failure and do not know.Also inconvenient during use.

In addition, general filter glass is installed in the front of camera lens with screw thread, so the optical filter diameter is big, and crudy is not easy to guarantee, bothers very much when changing the outfit.

Summary of the invention

The purpose of this utility model is to provide a kind of ultraviolet-infrared multiduty photographic means, and the shooting effect that causes owing to light path conversion is poor, volume big to overcome, shortcoming that can not close-perspective recording.

The technical solution of the utility model is: comprise camera lens, close-shot bellows, image intensifier, camera, camera, positive close-shot bellows one end that connects of camera, its other end is connected with camera lens, at the vertical image intensifier that is connected in the camera and the junction of close-shot bellows, the other end at this image intensifier connects camera, be connected a boxcar at described camera with the junction of close-shot bellows, the fixing wide spectrum beam divider that a light path with camera light path and image intensifier is 45 is set therein.

Also comprise being positioned at the filter slide opening of described boxcar, insert the filter that is slidingly matched with it within it near close-shot bellows place.

Described filter comprises rectangle slide plate, optical filter, and circular filter uniformly-spaced is arranged on the slide plate, has and the equally spaced locating slot of optical filter at the edge, a long limit of slide plate.

Described camera is the single lens reflex type camera, and described camera lens is wide spectrum camera lens.

The utility model is owing to adopted fixing wide spectrum beam divider to be fixed in the boxcar with 45, therefore change without any need for the parts of activity, reduced operation item, avoided vibrations, displacement, so the package unit volume is little, in light weight, light path short.Can carry out infinity to 1 fully so add the camera lens and the close-shot bellows of the transformation of the way with this device: 1 search, observe, take pictures.Avoided also simultaneously that the photograph light path is not opened, disalignment etc., to the situation that the failure of taking a picture is not known.Slidingtype filter of the present utility model can slide in chute easily and replace.Because optical filter is in the place behind the camera lens, so the diameter of optical filter can dwindle greatly, not only can improve the quality of optical filter but also can improve the susceptibility of complete machine.

Embodiment

Referring to Fig. 1, the utility model comprises wide spectrum camera lens 1, close-shot bellows 2, image intensifier 5, camera 6, camera 7.The positive ends that connect close-shot bellows 2 of camera 7, its other end is connected with camera lens 1, is connected also vertical connection image intensifier 5 of boxcar 8 between camera 7 and close-shot bellows 2, at its outer end connection camera 6.The fixing wide spectrum beam divider 4 that a light path with the light path of camera 7 and image intensifier 5 is 45 is set in boxcar 8.Near close-shot bellows 2 places one filter slide opening 81 is arranged at described boxcar 8, insert the filter 3 that is slidingly matched with it within it.Described camera 7 is the single lens reflex type camera.

Referring to Fig. 2, described filter 3 comprises rectangle slide plate 31, optical filter 32, and circular filter 32 uniformly-spaced is arranged on the slide plate 31, has at a long edge of slide plate 31 and optical filter 32 equally spaced locating slots 33.Filter 3 also can be Wheel-type.

The utlity model has following characteristics:

1 its critical component only is wide spectrum (ultraviolet one the is infrared) beam divider 4 that a fixing 45 is placed, and this device volume is little, in light weight, can make image intensifier 5 and camera 7 be in same axle center after once adjusting, and is constant on the same focal plane.

2 slide types (or Wheel-type) filter 3 makes the displacement of optical filter 32 more convenient, quick, light.Mid-optical filter has reduced diameter than existing preposition filtering type optical filter, has guaranteed quality, has improved susceptibility.

When using this device, at view window camera 6 has been installed, and AV is provided delivery outlet, can insert any surveillance (LCD monitor, liquid crystal glasses, notebook computer, video camera, video recorder etc.), make observing effect better, operation is very easy.The fatigue and the long-time dizzy symptom that causes of observing of eye have been reduced.
