Abstract
An optical imaging lens group, from an object side to an image side sequentially includes: a meniscus-shaped first lens having a negative refractive power and a convex surface facing the object side; a meniscus-shaped second lens having a negative refractive power and a convex surface facing the image side; an aperture stop; a third lens having a positive refractive power and two convex surfaces respectively at the object side and the image side; a fourth lens having a positive refractive power and two convex surfaces respectively at the object side and the image side; a fifth lens having a negative refractive power and two concave surfaces respectively at the object side and the image side; a sixth lens having a positive refractive power and two convex surfaces respectively at the object side and the image side; and a filter.
