A2
Abstract:
This invention relates to a small taking lens which is small because pixel sizes are small, but can implement a high-resolution camera by being combined with a high-resolution image sensor. The small taking lens of the present invention comprises in order from an object side: an aperture; a first lens which has positive refractive power and has a convex shape on the object side; a second lens which has negative refractive power, has a paraxial plane shape on the object side, and has an aspherical shape on the upper side; a third lens which has positive refractive power and has a concave meniscus shape on the object side; and a fourth lens which has negative refractive power and has a convex shape on the object side, wherein the Abbe numbers of the first, third and fourth lenses are between 40 and 50.
