Problems solved by technology
Because the circular lens is relatively thick, there will be more air bubbles inside and cracks on the surface during production, resulting in a low yield, resulting in a lot of waste, and in the process of production, processing and installation, it is easy to produce certain stress deformation due to the need to compress the lens. This affects the effect of observing celestial bodies, and the thick glass lens will cause inconvenience in the assembly process; the fixing device includes several buckles to fix the lens, but some of these buckles are placed on the surface of the lens to make the lens The surface is partially blocked, which affects the observation range and observation effect, and the fixture requires a large number of parts, making the assembly more complicated

Embodiment Construction
[0025] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0026] refer to Figure 1 to Figure 3 , a lens assembly of an astronomical telescope, which includes a pair of lenses 1 and a lens seat 3 fixedly connected with the pair of lenses 1 .
[0027] The pair of lenses 1 are respectively circular flat glass, and are separated from each other by a certain distance. Wherein, a through-hole 12 is provided at the center of the inner lens 1 , and the above-mentioned lens holder 3 can be inserted into the through-hole 12 .
[0028] The above-mentioned lens assembly also includes a plurality of glass tubes 5 , all of which are hollow in different sizes, and are clamped between the pair of lenses 1 .
[0029] The above-mentioned lens seat 3 is generally hollow columnar, and has an opening 30 along the axial direction. One end 32 of the lens holder 3 is installed on the objectiv...

The invention discloses a lens assembly of an astronomical telescope and an assembling method thereof. The lens assembly comprises a pair of lenses and a lens seat fixedly connected with the lenses. A plurality of glass tubes are arranged between the lenses. The lenses are fixedly connected with the lens seat by a mixture of glue and expandable polystyrene (EPS) foam. The lens assembling method is that the lenses and the lens seat are fixedly connected by the mixture of the glue and the EPS foam, thus the stress of the glue on the lenses is reduced by the EPS foam, the lenses are prevented from physically deforming, and the required parts for fixing the lenses are also reduced.
Description
technical field [0001] The invention relates to a lens assembly of an astronomical telescope and an assembly method thereof. Background technique [0002] Today's astronomical telescope lens assemblies typically consist of a thick circular lens and a fixture that secures the circular lens to an objective lens mount. Because the circular lens is relatively thick, there will be more air bubbles inside and cracks on the surface during production, resulting in a low yield, resulting in a lot of waste, and in the process of production, processing and installation, it is easy to produce certain stress deformation due to the need to compress the lens. This affects the effect of observing celestial bodies, and the thick glass lens will cause inconvenience in the assembly process; the fixing device includes several buckles to fix the lens, but some of these buckles are placed on the surface of the lens to make the lens The surface is partially blocked, thereby affecting the observat...
