Description

A kind of poly capillary optic

Technical field

The utility model relates to X ray applied technical field, especially relates to a kind of poly capillary optic.

Background technology

The eighties in last century, the scientist of China scientist and USSR (Union of Soviet Socialist Republics) uses multiple capillary parallel beam on synchrotron radiation X ray is analyzed, and has carried out ground-breaking work.Due to the characteristic that can not focus on of X ray, the necessary collimated beam of X-ray diffraction analysis adopts little rope to draw slit usually.But traditional rope draws slit can only in a direction perpendicular to slit to the restricted effect of light, this makes line source all be subject to very large loss as incident intensity and diffraction intensity in the device of light source.

Fig. 1 shows traditional rope and draws slit needle to the light path schematic diagram of line source, and wherein, (a) of Fig. 1 is front elevation, and (b) is the side view drawing slit from left side rope, and (c) is vertical view.The diffractive optical element that traditional rope shown in Fig. 1 draws slit to be made up of the foil that a group is equidistantly parallel to each other.Namely rectangle in (a) of Fig. 1 represents foil, to be drawn after slit 20 send parallel beam by the light of line source 10 outgoing through rope, finally arrives sample 30.In (b) of Fig. 1, middle black rectangle represents line source.Five vertical vertical lines are sheet metals of parallel equidistant arrangement, namely represent that rope draws slit.In (c) of Fig. 1, the solid rectangular of left end represents line source.5 middle horizontal lines represent the sheet metal of 5 parallel equidistant arrangements, and namely rope draws slit.

Because traditional rope draws slit to form by series of identical rectangular metal sheet is arranged in parallel, so the linear light sent for line source can only in a restricted effect in direction perpendicular to metal covering, cause light loss larger, thus can affect the resolution of imaging on sample.

Therefore, how to reduce the loss of incident light, promote resolution, being one has problem to be solved.

Embodiment

Below, preferred implementation of the present utility model is described in detail.The example of these preferred implementations illustrates in the accompanying drawings.Shown in accompanying drawing and the embodiment of the present utility model described with reference to the accompanying drawings be only exemplary, and technical spirit of the present utility model and main operation thereof are not limited to these embodiments.

In the utility model, the feature for line source designs the poly capillary optic of square-section, replaces traditional rope to draw slit with this poly capillary optic.In other words, the utility model provides a kind of novel rope made based on multiple capillary principle to draw slit, to improve the utilization factor of line source in X-ray diffraction analysis.

Fig. 2 is that in the utility model, poly capillary optic is for the light path schematic diagram of line source, and wherein, the front view that (a) is light path, (b) is from side view during left side, and (c) is vertical view.

In the utility model, poly capillary optic such as can be multiple capillary lens, these multiple capillary lens comprise the tube bank of many capillaries composition, the inlet end of multiple capillary lens (tube bank) is the rectangle corresponding with the shape of line source, for receiving the X ray that line source sends, the endpiece of multiple capillary lens is also rectangle, rectangular long limit, endpiece place and broadside are parallel to rectangular long limit, inlet end place and broadside respectively, further, the rectangular wide wide change compared to inlet end place in endpiece place is large.Be explained in more detail below.

Single capillary based on total reflection is the very thin and glass tube of inwall unusual light of caliber, normally 0.1-10 μm.When X ray is to be less than the outer angle of total reflection of glass incident, the outer total reflection of X ray will be there is.The X ray angle of total reflection of material is usually all very little, wants the transmission direction being changed X ray by reflection, just needs repeatedly outer total reflection, the principle of Here it is capillary conduction X ray.

In embodiment of the present utility model, hundreds of thousands can be used to arrive the tube bank of nearly up to a million kapillary formation, thus formation poly capillary optic, still based on total reflection, X ray, in hollow kapillary, carries out reflection repeatedly, plays the effect of waveguide, both can linear transmission, also can certain radius-of-curvature conduct.

With reference to Fig. 2, by the light of line source 100 outgoing, drawn slit (i.e. multiple capillary formed tube bank) 200 to collect at inlet end by novel rope and be transmitted to endpiece, go out to penetrate collimated beam light, final arrival sample 300 is surperficial.Novel rope draws slit left end to be inlet end, and right-hand member is endpiece.The xsect of inlet end and endpiece, the xsect of the tube bank of also i.e. multiple capillary formation, all design becomes rectangle.Preferably, the rectangle of endpiece and the rectangle of inlet end coaxial.Especially the size of inlet end, can do corresponding change according to the size of line source.Not etc., these two rectangular length can be inequal for endpiece and two rectangle width corresponding to inlet end.In one embodiment, the thicknesses such as every capillary is, namely the incidence end of every capillary is equal with exit end rugosity, and many capillaries are different with the density that endpiece is arranged at inlet end, causes the rectangular cross section of endpiece and inlet end tube bank to vary in size.In (b) of Fig. 2, middle rectangle represents the inlet end profile of many tube banks with kapillary composition, and outmost rectangle represents the endpiece profile of tube bank.The vertical view of the respective optical path of poly capillary optic has been shown in (c) of Fig. 2, and in figure, middle rectangle is the vertical view of multiple capillary tube bank.The tube bank obtained shown in Fig. 2 can be suitably bent by making kapillary.

Be illustrated in figure 3 the sectional view intercepted along inlet end of the tube bank that multiple capillary is formed.Kapillary shown in Fig. 3 is only signal, and is not limited to shown quantity, and multiple capillary bundle is composited by thousands of parallel single capillary, and arrange rectangularity shape.

The X ray sent to make line source is parallel arrival sample after multiple capillary lens, the multiple capillary horizontal arrangement in parallel to each other at the endpiece place of multiple capillary lens, thus from the X ray of inlet end incidence from endpiece exiting parallel.

In the utility model, rope is replaced to draw slit with poly capillary optic, just can in the two directions to the restricted effect of incident light, this device to being at this moment irradiated to sample can remain a branch of parallel X-ray.

That is, line source light out is effectively collected by poly capillary optic of the present utility model, thus can limit incident light in both direction, decreases the loss of diffraction intensity and incident intensity.

It should be noted that, above-described embodiment is only and the utility model and unrestricted the scope of the claims of the present utility model is described, any based on equivalents technology of the present utility model, all should in scope of patent protection of the present utility model.
