Description

Technical Field

[0001] The utility model relates to the technical field of telescopes, in particular to an impact-resistant and heat-resistant optical lens structure for telescopes. Background Art

[0002] A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects. It uses the refraction of light through lenses or the reflection of light by concave mirrors to make the light enter a small hole and converge to form an image, which is then seen through a magnifying eyepiece, also known as a "telescope for seeing afar".

[0003] The design of telescopes also takes into account their use in outdoor environments, so there are designs for waterproofing, dustproofing and impact resistance to ensure that telescopes can work properly and maintain excellent optical performance under various weather conditions.

[0004] However, most of the existing optical lens structures lack heat resistance and durability, which means that the service life of telescopes under high temperature or harsh conditions will be greatly shortened, and the optical materials may lose their original optical properties due to long-term exposure to high temperature environments. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an impact-resistant and heat-resistant optical lens structure for telescopes, aiming to improve the problem that most of the existing optical lens structures lack heat resistance and durability, which means that the service life of telescopes under high temperature or harsh conditions will be greatly shortened.

[0007] Further, the lens assembly includes a snap ring, the snap ring is fixedly connected to the right end of the lens barrel, a window piece is arranged inside the snap ring, and an end cover is arranged at the right end of the lens barrel.

[0008] Further, retaining rings are arranged between the lenses.

[0009] Further, a retaining ring is provided on the right side of the thirteenth lens.

[0010] The utility model has the following beneficial effects:

[0011] 1. In the utility model, after the trimmed lenses are detected and qualified again, they are installed in the aluminum alloy lens barrel, which can not only ensure the assembly accuracy of the lens, but also ensure that the optical lens can withstand the harsh force and heat environment.

[0012] 2. In the utility model, through the settings of the end cap and the window piece, it is convenient to protect the lens inside the optical lens barrel, ensure that the optical lens structure has good sealing performance, and can prevent dust, moisture or other pollutants from entering the lens interior, thereby maintaining its cleanliness and optical transparency.
