Description
Technical Field
The utility model relates to a telescope production and processing technology field, concretely an use range telescope optical system of combination prism.
Background
The basic principle of the optical system of the range-finding telescope is that laser is transmitted and received, and then the range-finding result is displayed by a display and observed through an ocular.
Patent numbers: 201710258575.7 discloses a laser range finding monocular, which comprises a casing, a power module, a telescope system, a laser emission system, a laser receiving system, a photoelectric processing unit, a data processing unit and a main control module, a display device for displaying the azimuth parameter value of an object to be measured processed by the data processing unit, wherein the display device is arranged in the casing at a position which does not shield the light path of the telescope system, a display surface for displaying the azimuth parameter on the display device is imaged through a parameter imaging objective lens and a focal plane shared by the telescope system so that an observer can simultaneously observe an object image and the azimuth parameter value of the object image through the telescope system, a light splitting film for preventing laser from entering and allowing white light to enter an eyepiece/eyepiece set is arranged in the telescope system, the laser emission system shares the objective lens/objective lens set of the telescope system to emit laser, and the eyepiece/eyepiece set is arranged in a monocular barrel at one side of the casing. It has the advantages of good expected remote effect and convenient distance measurement.
However, such an optical structure is complicated in arrangement, and is particularly large in the middle of the optical system, thick in the middle, relatively thin at the two ends, and the operating wavelength of the laser generator is 0.65um of red light, so that the display can generate halo and the observation is affected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an use range telescope optical system of composite prism adopts compact structure light path design thinking, with objective group, composite prism, eyepiece group design on same horizontal optical axis, compress whole telescope middle section, the design is accomplished the back, is unanimous with ordinary roof ridge telescope, can realize the general of telescope accessory production like this, need not set up the mould alone, saves the cost, is worth promoting.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an use range telescope optical system of combination prism, includes objective lens group, combination prism, eyepiece group, its characterized in that: an objective lens group, a combined prism and an eyepiece group are sequentially arranged along the reverse direction of an optical axis, a condensing lens is arranged at the lower end of the combined prism, and a laser generator or a receiver is arranged at the lower end of the condensing lens;
the combined prism comprises a roof prism, a half pentagonal prism and a wedge-shaped prism, the roof prism is installed on the left side of the ocular group, the lower portion of the roof prism is provided with the half pentagonal prism, the lower portion of the half pentagonal prism is provided with the wedge-shaped prism, the left side of the wedge-shaped prism is provided with a projection lens, the display is installed between the objective group and the combined prism, and the light of the projection lens is perpendicular to the display.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses a combination prism retraces the range finding light path to the main light path space, with the shared part space of main light path, reduces the telescope volume, realizes that laser range finding telescope is the same with ordinary telescope volume, and it is more convenient to use, and the accessory is also general accessory, and processing is convenient, and light is the total reflection design moreover, need not carry out the coating film in the light path and eliminate red light to user's influence.

Detailed Description
Referring to fig. 1, a distance measuring telescope optical system using a combined prism includes an objective lens group 1, a combined prism 13, and an eyepiece group 6, and is characterized in that: an objective lens group 1, a combined prism 13 and an ocular lens group 6 are sequentially arranged along the reverse direction of an optical axis, a condensing lens 5 is arranged at the lower end of the combined prism 13, and a laser generator or a receiver 4 is arranged at the lower end of the condensing lens 5;
the combined prism 13 comprises a roof prism 10, a half pentagonal prism 11 and a wedge-shaped prism 3, wherein the roof prism 10 is arranged on the left side of an ocular group 6, the half pentagonal prism 11 is arranged on the lower part of the roof prism 10, the wedge-shaped prism 3 is arranged on the lower part of the half pentagonal prism 11, a projection lens 2 is arranged on the left side of the wedge-shaped prism 3, a display 12 is arranged between the objective group 1 and the combined prism 13, and the light of the projection lens 2 is perpendicular to the display 12. In the whole light path design process, the combined prism 13 is utilized to convert the laser emitted by a laser generator or a receiver 4 into the main light path of a telescope optical system, the volume in the middle of the telescope is reduced, the structure of the telescope is changed, the short and thick structure of the telescope laser range finder is adjusted into the long and thin structure of a roof straight tube telescope, meanwhile, the laser emitted by the laser generator or the receiver 4 realizes a total reflection mode, and the influence of red light rays on the optical system is eliminated without coating films on the lenses in the whole light path.
