Description

Technical Field

[0001] The utility model relates to the technical field of field lenses, in particular to a self-cleaning aspheric single-piece field lens. Background Art

[0002] Aspheric single-piece field lenses are specially designed lenses that combine the characteristics of aspheric lenses and field lenses. Aspheric single-piece field lenses play an important role in optical systems, especially in applications requiring high precision and high resolution, such as photography and laser scanning. This lens design can theoretically minimize spherical aberration while optimizing optical performance. However, current aspheric single-piece field lenses still have the following shortcomings:

[0003] For example, the patent document with application number 202023167541.3 discloses an aspherical single-piece field lens. This aspherical single-piece field lens can change the position of the aspherical lens inside the lens barrel by twisting the adjustment seat. The change in the position of the aspherical lens can refocus the laser, which makes it unnecessary to disassemble the device for adjustment, thereby reducing the maintenance time of the device, which is conducive to improving overall work efficiency. However, during use, dust and other impurities will adhere to the surface due to static electricity, and water stains are easily left, causing the surface to become dirty and affecting the field of view.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a self-cleaning aspheric single-piece field mirror is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a self-cleaning aspheric single-piece field lens to solve the problems raised in the above background technology.
