The invention relates to the optical instrument and can be used in goniometric devices types of theodolites, tacheometers, goniometers.Known combinations of complex prisms for finders 
In them the line section or junction line between the two prisms (two parallelepiped, the pentaprism offset part), or smooth edge to reflect the EPA).Known system device for combining images in goniometric devices, which allow to obtain a thin dividing line between the two images, such as strokes opposite sides of a limb or the image of rails and lines nomograms  used a system with two prisms, for example, two glued together along a common edge of a parallelepiped, the pentaprism with an offset part, rectangular prism, glued with a wedge-shaped prism.The drawback of such a device for combining images is that they are designed only to combine two images.The aim of the invention is the possibility of combining the three images.The objective is achieved by the fact that improved the known device for combining images in goniometric devices, consisting of two prismatic elements.The improvement lies in the fact that it introduces a flat plate mounted between the prismatic elements and bonded with them, and at least one outer face of the plate parallel to the focal plane of the eyepiece goniometric device.The ribs are glued prismatic elements can be placed in the focal square is to be applied reflective layers, equal edges which are located in the focal plane of the eyepiece goniometric device.In the device with reflective layers can be entered at least one additional plate the same size as the first plate and glued it on the overall surface on which the line is marked mesh, installed in the focal plane of the eyepiece telescopes, while the first plate is bonded to the first prism and the second plate with the second prism.In this device, at least one outer face of the plate and the corresponding faces of the prisms can be pasted in a plane-parallel plate parallel to the focal plane of the eyepiece goniometric device, or convex collective lens.The invention is illustrated in the examples of execution represented in Fig. 1-6.In Fig. 1-6 are indicated: the first prism element 1, the second prismatic element 2, the plate 3, the edges of prism elements in the focal plane of the eyepiece 4, the edge of the reflecting layer 5. The swing beams shown by arrows 6-8.In addition, the device can be introduced additional plate 9, a collective lens 10, the grid line 11. While in the drawing: the front line of the eyepiece 12, peraea 15, the image in the right part of the field of view of the eyepiece 16, the image in the Central part of the field of view of the eyepiece 17.In Fig. 1 shows a variant with two parallelepipeds 1, 2 and plate 3, Fig. option 2 with the pentaprism 1 offset part 2 and plate 3, Fig. option 3 with rectangular prisms 1 and 2, and plate 3, Fig. 4 a variant of the device with two rectangular prisms 1 and 2, and plate 3, supplemented collectively lens 10 of Fig. 5 shows a variant with an additional plate 9, line grid 11, a plane-parallel plate 4 and team 10.In Fig. 4 and 5 shows also the front lens of the eyepiece 12 and the front plane of the eyepiece 13. In Fig. 6 shows the field of view eyepiece goniometric device type tachometer in which the Central part of the field of view of the eyepiece contains the image of the subject areas and, in particular, Reiki, and in the left and right parts of the field of view of the eyepiece is portrayed line rangefinder and arrogant charts. Image Reiki installed close to the dividing line of the left and Central fields and possible reference along the lines of the charts, as in the total station Gummer-Vennela.Radiation from three independent iStock radiation released as a single stream 6-8, three images constructed by these streams are separated from each other by a thin separating edges, which are edges of the prism 4 or edges of the reflecting layer 5.A device for combining images consider the example of combining images of three objects, which are constructed of three optical systems. For example, in the center of the lens telescopes built the image of Reiki, one of the side sections of the field of view based image rangefinder nomograms, and the other vysokomernoy nomograms. In a variant of the device of Fig. 1 light from the lens optic pipe 7 passes through the plate 3 and depicts the rail in the plane of the ribs 4. Light from the distance measuring monogram 6 runs parallel to the axis of the telescope enters the prism 1 and creates images in the same plane. Similar beam 8 is built vysokomernoy nomograms through the prism 2. All three images are constructed in the same plane and can simultaneously be viewed through the eyepiece. The dividing line is thin rib 4 on the output device can produce a reference Reiki on line nomograms.Variant of the device shown in Fig.2, differs in that the light from the nomograms posts. 3 corresponds to the case when the light from the nomograms arrives at an angle of 90aboutto the axis of the telescopes, and the dividing lines are straight edge of the reflecting layer 5 inside the unit. As the rest of the drawings, the light from the lens telescopes 7 is the device through a planar face on the inlet and outlet of the device.In the case depicted in Fig.3, the edges of the prisms and plates, glued together, can get in the course of the rays going to the eyepiece, and to worsen the conditions of observation shared objects. Experimental measurements have shown that the edges of the prisms and plates, the angle at which less direct, because of microscale have a width 0,03-0,09 mm Though they are far from the focus of the eyepiece and the image observer does not see, it turns out some of the shading image.In this regard, the outer face of the plate and the adjacent faces of the prisms glued plane-parallel plate or convex collective lens. The glue fills the cavity microscale, and darkening due to this almost becomes invisible. Naturally, the refractive index of the adhesive and the glass microscale should be agreed. Plane-parallel plate or convex collective lens can imeetsya simultaneous assessment (and reading) of the mutual position of the three objects instead of individual otschityvaniya on different reading devices, which allows you to accelerate the angular works. 1.
