Abstract
The utility model discloses a variable light source for illumination of optical system target surface, including the light source that sets gradually, hair glass, collimation camera lens subassembly with assemble lens group spare, the hair glass set up in the sleeve with collimation camera lens subassembly, the light source with assemble lens group spare and set up respectively in the sleeve both ends, collimation camera lens subassembly is used for being adjusted into the parallel light with the emergent light, collimation camera lens subassembly is the same with the structure of assembling lens group spare, and relatively backward setting. The utility model discloses the light source illuminates a set of collimation camera lens behind hair glass homogenizing, can make the light of scattering become parallel light source. Add a set of the same camera lens again, the reversible principle of light path is utilized to reverse the use, and the parallel light just can become the convergent light outgoing, and the light intensity obtains improving, can concentrate the illumination to the graticule. The utility model discloses the messenger assembles the light source only need use a set of camera lens of dismouting with the switching between the parallel light source, simple structure, simple to operate, but fast switch over light source form.
Description
Technical field
The utility model belongs to exact instrument mechanical-optical setup field, relates to a kind of type variable light source for the illumination of optical system target surface.
Background technology
No matter be transmission-type parallel light tube, or reflective parallel light pipe, be all the graticule be placed on light illuminating on focal plane, realize the function that infinite distance target is provided.Parallel light tube generally uses bulb and frosted glass to form the Lights section, illuminates graticule.According to different measurements application, sometimes need to add optical filter after light source, make quasi-parallel light source and carry out face illumination; Sometimes need centralized lighting, make the converging light illumination that brightness is stronger, namely different measurement application needs different lighting systems, to obtain applicable light intensity and light distribution, otherwise may produce measuring error.When measuring application and changing, usually need to change lighting source, light path also needs again to debug, very loaded down with trivial details.
Utility model content
For the above-mentioned deficiency of prior art, the utility model proposes a kind of lightweight and portable in volume, be convenient to the type variable light source installed and used, can according to requirements switch between directional light and converging light, after switching, light path does not need to readjust.
The technical solution of the utility model is as follows:
A kind of type variable light source for the illumination of optical system target surface, comprise the light source, frosted glass, collimation lens assembly and the collective lens assembly that set gradually, described frosted glass and collimation lens assembly are arranged in sleeve, described light source and collective lens assembly are arranged at sleeve two ends respectively, described collimation lens assembly is used for emergent light to be adjusted to directional light, described collimation lens assembly is identical with the structure of collective lens assembly, and relatively oppositely arranges.
As further improvement of the utility model, described collective lens assembly comprises collective lens, assembles picture frame and convergent mirror trim ring, described collective lens is fixedly installed on to be assembled in picture frame, described convergent mirror trim ring is arranged at assembles inner edge, picture frame outer end, and the inner of described convergence picture frame is removably fixedly connected with sleeve.
As further improvement of the utility model, described light source is the Halogen lamp LED being furnished with louvre.
The utility model has the following advantages:
A kind of type variable light source for the illumination of optical system target surface of the utility model, improve light-source structure carrying out design, light source, after frosted glass (can be replaced optical filter) homogenize, illuminates one group of collimation camera lens, the light of scattering can be made to become source of parallel light.Add one group of identical camera lens again, oppositely use, utilize light path principle of reversibility, directional light just becomes converging light outgoing, and light intensity is improved, and can carry out centralized lighting to graticule.The utility model makes the switching between convergent light source and source of parallel light only need use dismounting one arrangement of mirrors head, and structure is simple, easy for installation, can toggle lights form fast.
Accompanying drawing explanation
Fig. 1 is convergent light source structural drawing of the present utility model.
In figure: 1 light source; 2, frosted glass; 3, light source urceolus; 4, inner core; 5, camera lens is collimated; 6, collimating mirror trim ring; 7, collective lens; 8, picture frame is assembled; 9, convergent mirror trim ring; 10, light source base.
Embodiment
Principle of the present invention and embodiment is described in detail below in conjunction with accompanying drawing.
General lighting mechanism uses bulb to illuminate direct illumination graticule after frosted glass, and such light intensity is more weak, may impact follow-up use, and the present invention has carried out global design to the Lights section.
The structure of a kind of type variable light source for the illumination of optical system target surface of the utility model as shown in Figure 1, comprises the light source 1, frosted glass 2, collimation lens assembly and the collective lens assembly that set gradually.Frosted glass 2 and collimation lens assembly are arranged in sleeve, and light source 1 and collective lens assembly are arranged at sleeve two ends respectively.Collimation lens assembly is used for emergent light to be adjusted to directional light, and collimation lens assembly is identical with the structure of collective lens assembly, and relatively oppositely arranges.Sleeve comprises light source urceolus 3 and inner core 4, and it is outside that light source urceolus 3 is sheathed on inner core 4.Whole type variable light source is supported by light source base 10.
As preferred implementation of the present utility model, collective lens assembly comprises collective lens 7, assembles picture frame 8 and convergent mirror trim ring 9.Collective lens 7 is fixedly installed on to be assembled in picture frame 8.Convergent mirror trim ring 9 is arranged at assembles inner edge, picture frame 8 outer end, and the inner assembling picture frame 8 is removably fixedly connected with sleeve.
As preferred implementation of the present utility model, collimation lens assembly comprises collimation camera lens 5, collimating mirror trim ring 6.Convergent mirror trim ring 6 is arranged at inner edge, sleeve outer end.
As preferred implementation of the present utility model, the bulb 1 of light source adopts 12V, the Halogen lamp LED of 35W, and be furnished with louvre, after frosted glass 2 (or visible ray monochromatic filter) in structure is illuminated, through the collimating mirror 5 of lens barrel front end, scattered light is become the outgoing of quasi-parallel light, can the target surface of uniform illumination larger area, the target of an infinite distance is provided.
When using parallel light tube to detect resolution or the disc of confusion size of a certain system, target position will use resolving ability plate or star tester as target, small size resolving ability plate and undersized asterism, higher light intensity is needed to illuminate as far as possible, emergent light of the present invention is directional light, utilizes light path principle of reversibility, adds one group of collective lens after light-emitting window, irradiate again, greatly improve the brightness of target target surface.
Independent collective lens is identical with collimating mirror parameter, uses screw thread to connect, and removes and installs simple, is convenient to toggle lights form.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
