Document Type and Number:
Japanese Patent JP6802612
Kind Code:
B2
Abstract:
The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens includes, from an object side to an image side: an aperture; a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a negative refractive power; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power; and a sixth lens having a negative refractive power. The camera optical lens satisfies following conditions: 1.09≤n4/n1≤1.30; and −2.00≤(R1+R2)/(R1−R2)≤−1.50, where n1 denotes a refractive index of the first lens; n4 denotes a refractive index of the fourth lens; R1 denotes a curvature radius of an object side surface of the first lens; and R2 denotes a curvature radius of an image side surface of the first lens.
