Summary:The invention relates to the field of optical devices, in particular to an optical lens component used in a 0.3-mega-pixel camera module of a mobile communication tool. The optical lens component comprises a fixed diaphragm, a lens group and a glass optical filter, wherein, the lens group comprises a first lens and a second lens which are sequentially arranged from object space to image space on the same optical axis, the surfaces of the first lens and the second lens are aspheric surfaces, and the aspheric formula is shown in the specification. The optical lens component has the advantages that the lens group has only two lens, the lenses of the optical lens component can be matched with each other to effectively reduce the height of the lens to less than 1.7mm within the range of a vision angle of more than 80 degrees, and meanwhile the aberration of light can be effectively eliminated by adopting aspheric lenses; and by adopting the plastic lenses, the processing difficulty of the glass lenses is avoided,
