Miniaturized lens assembly

A miniaturized lens assembly comprises a first lens, a stop, a second lens, a third lens, a fourth lens and a fifth lens, all of which are arranged in sequence from an object side to an image side along an optical axis, wherein:

• the first lens is made of plastic material, is a meniscus lens with negative refractive power, and comprises a convex surface facing the object side;
• the second lens is made of plastic material and is a biconvex lens with positive refractive power;
• the third lens is made of glass material and is a biconvex lens with positive refractive power;
• the fourth lens is made of glass material, is a biconcave lens with negative refractive power, and is adhered to the third lens to form a compound lens;
• the fifth lens is made of plastic material, is a meniscus lens with positive refractive power, and comprises a concave surface and a convex surface;
• the convex surface of the fifth lens faces the object side;
• and
• at least one of the concave surface and the convex surface of the fifth lens is an aspheric surface.
