Description

Technical Field

[0002] A lens is an optical element made of transparent material with a spherical surface. It is composed of several lenses. There are two types of lenses: plastic lenses and glass lenses. Glass lenses are more expensive than plastic lenses. The lens structures usually used in cameras are: 1P, 2P, 1G1P, 1G2P, 2G2P, 4G, etc. The more lenses, the higher the cost. Therefore, a good quality camera should use a glass lens, which has better imaging effect than a plastic lens and plays an important role in astronomy, military, transportation, medicine, art and other fields.

[0003] The existing optical lens structure is relatively simple, and most of them use a single lens, which results in the product's visual anti-glare function and mixed light effect being average and the use effect is poor. For this reason, we propose a freely spliced ​​secondary light cone correction optical lens. Utility Model Content

The buckles and the clamping holes are movably connected, and grooves are fixedly opened on the surface of the second lens. The grooves are provided in multiple groups and have the same structure.

[0009] Preferably, a second refractive surface is fixedly installed above the first refractive surface, and a second refractive light-controlling surface is fixedly connected to the outer side of the second refractive surface.

[0010] Preferably, a mounting hole is fixedly opened in the middle of the surface of the second lens, and a positioning mechanism is fixedly connected to the middle of the bottom surface of the second lens.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
