| titleOfInvention | A high-resolution lens with a periscope small head |
| abstract | The utility model relates to a periscope type small head high-resolution lens, the technical point of which is that, from the object side to the image side, it sequentially includes: a negative refractive force, the object side surface is concave at the optical axis, and the image side surface is concave at the optical axis. The first lens with convex surface at the axis; diaphragm; the second lens with positive refractive power, the image side is convex at the optical axis; the prism with the angle between the reflective surface and the optical axis is 45°; with negative refractive power, the image side A third lens with a concave surface at the optical axis and at least one aspheric surface; a fourth lens with a positive refractive power, the image side is convex at the optical axis and at least one surface aspheric; with a positive refractive power, the image side A fifth lens with a convex surface at the optical axis and a concave surface on the object side at the near-optical axis; a sixth lens with negative refractive power, an M-type shape and a convex surface on the object side at the optical axis. Not only the size of the head is small, which can effectively increase the screen ratio, but also has a high resolution, which can shoot clearer images and meet the miniaturization requirements of the lens. |
