Patent ID: 11874445

Abstract:
The present disclosure discloses a camera optical lens including eight lenses which are, from an object-side to an-image side: 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 positive refractive power, a sixth lens having a refractive power, a seventh lens having a negative refractive power and an eight lens having a negative refractive power, which satisfies following conditions: 0.95≤f/TTL; −5.00≤f2/f≤−2.00; and 0.40≤(R9+R10)/(R9−R10)≤1.00; where TTL denotes a total optical length from an object-side surface of the first lens to an image surface of the camera optical lens along an optic axis; f denotes a focal length of the camera optical lens. The camera optical lens can achieve good optical performance while meeting the design requirement for long focal length and ultra-thinness.
