Abstract
The disclosure provides an optical lens system and a vehicle camera. From an object side to an imaging surface, the optical lens system sequentially includes a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a positive refractive power; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power, the fourth lens and the fifth lens constituting a cemented lens; a sixth lens having a positive refractive power; a seventh lens with a negative refractive power; a stop disposed between the first lens and the third lens. The lens of the present disclosure not only has thermal stability, but also has extremely high resolution for the objects that emit or reflect monochromatic lights of different wavelengths, so as to meet the requirements of the driverless vehicle system on the lens.
