Abstract

The invention discloses an optical imaging lens, which sequentially includes first, second, third, fourth, fifth, sixth and seventh lenses from the object side to the image side. The present invention controls the concavo-convex surface arrangement of each lens surface, and conforms to the sum of six air gap widths (AAG) on the optical axis between the first lens to the seventh lens, and the light gap between the first lens to the seventh lens. The relationship between the maximum value (Gmax) of the six air gaps on the axis and the minimum value (Tmin) of the seven lens thicknesses on the optical axis from the first lens to the seventh lens is the limit of AAG / (Gmax+Tmin)≦1.700 Under this condition, the effect of maintaining good optical performance and expanding the viewing angle is achieved.

Description

technical field [0001] The invention relates to an optical imaging lens, in particular to a seven-chip optical imaging lens. Background technique [0002] The specifications of consumer electronic products are changing with each passing day, and the pursuit of lightness, thinness and compactness has never slowed down. Therefore, the specifications of key components of electronic products such as optical lenses must continue to improve in order to meet the needs of consumers. The most important characteristics of optical lenses are imaging quality and volume. In addition, the characteristics of improving the angle of view are becoming more and more important. Among them, in terms of imaging quality, with the advancement of image sensing technology, consumers' requirements for imaging quality will also increase. Therefore, in the field of optical lens design, in addition to pursuing thinner lenses, lens imaging must also be considered. quality and performance. [0003] Howev...
