Invention Description (2) If the thickness of the beam splitter is L n' = L/1· 5=0·67L, and no n, that is, the larger the image orientation, the optical path The difference is also greater. The digital telescope can be divided into two directions by using a cubic prism beam splitter between the focus F' and the other side to reflect the light. In the cube, the spectroscope is fixed in the moving or rotating mechanism to separate the optical path of the spectroscope to achieve simple observation and aiming. For the prior art, the following problems are solved from the spectroscope: First, the required size is large. , 'and the precision of the bismuth material into the second' plated optical mode is easy to produce three, due to the large size, the optical path is poor. ^Cubic 稜鏡 稜鏡 = 论 论 论 论 论 论 论 论 论 论 论 论 论 论 论 论It is necessary to divide into two parts and the second energy loss is large, which will affect the use of the target seeding function. It is necessary to correct the movement when the thickness of the beam is added to the beam splitter. · 3 3 L distance · The above splitting of the imaging surface to be moved The principle is to mirror the beam splitter, make it transparent, all the way to reach the image sensor, the light mirror is set, the spotlight is in the way, the second is placed in the telescope, and the light path between the quasi-photographs itself, the optical path of the glass is L / optical path difference AzL-L / 3 The thicker distance of the dichroic prism is also greater.

Inventive Note (3) When the pure observation function is used, the spectroscope can be removed and lost, so that the observation alone becomes more and more, and the aunt. In this way, although the light energy loss can be reduced, the light is generated by visual observation of the light path, and the beam splitter is moved in and out. Obviously, there are two ways to know: = and the eyepiece needs to be re-invented [invention], and lost. The main object of the present invention is to provide a light-path differential optical device in an optical path, a direct system: a convergence and removal process of the imaging system, and an objective lens and an eyepiece: an inter-mirror shift: in the process of observation or photography switching It is easier and more convenient to use it without change.

The ratio of the area of the cut surface of the ridge is 5% to 30%.

Page 7 1269888 Amendment No. 94106590 V. Invention Description (4) J. As shown in the fourth and fifth figures, the mirror 8 is provided with a 'through hole 9' axis. The line coincides with the optical axis 12 and is at an angle of 45 degrees to the reflecting surface of the mirror 8. The mirror 8 can be made of flat glass or other materials, and its reflecting surface is plated with a total reflection film 10 (as shown in the fourth figure); and the receiver 7 is provided with a total reflection of the mirror 8 On one side of the diaphragm, Λ = the size of the aperture d of the central through hole 9 of the mirror 8 is surrounded by the through hole 9 : the area of the area and the spot of the objective lens i imaging beam on the mirror 8 The ratio of the area is generally in the range of 5% to 30%, and is usually about 1%, and the brightness of the image receiver 7 after the splitting is uniform can be ensured in the range of 5% to 3%. When the ratio is greater than 30%, the image formation on the image receiver 7 will cause a cutting phenomenon due to an increase in the aperture of the through hole 9, (ie, the through hole 9 is too large to cut the main light), and the light is present. The difference between bright and dark unevenness, and the loss of the image in the center of the image field or the cornering of the four corners of the image field cannot be applied to the image system at all; in addition, when the ratio is greater than 3〇%, it will be paid more. The mirror 8 has a large volume, a heavy weight, a high cost, difficulty in production, and the like. In addition, when the ratio is less than or less, it will cause the shirt to be imaged without any use value on the image system. In order to have both the digital observation and the smart camera function, the mirror 8 is supported by a moving or rotating mechanism and switches between two operating states of moving in and out of the optical path. The working principle of the invention is to move the mirror 8 with the through hole 9 in the center into the optical path. As shown in Fig. A, the light in the central portion of the optical path passes through the central through hole 9 to reach the focal plane, as shown in the shaded portion in the figure. Most of the remaining light is reflected by the spot reflection surface outside the center through hole 9 of the mirror 8, forming another path of light.

From the comparison of the sixth figure A and B, it can be seen that the distance between the two paths of light from the spectroscopic surface to the imaging surface is equal, that is, L j L 2 . When used alone for visual aiming observation, the mirror 8 is moved out of the light I. The light passing through the objective lens 1 2 3 is not restricted by the central through hole 9 of the mirror 8, and is imaged in the eyepiece 2 (as shown in the seventh figure). In the field of view, 'there is a book that can be obtained. D ▲ is used for photography. The mirror 8 with the through hole 9 in the center is moved into the light. The light is divided into two parts, and the light passing through the center through hole 9 is eight.
