High-magnification power eyepiece

The utility model provides a high-magnification power eyepiece. The high-magnification power eyepiece includes a doublet lens and a single lens; a positive lens and a negative lens are glued together so as to form the doublet lens; a convex surface of the doublet lens, which has negative refractive power, is an observation surface; a concave surface at the other side of the doublet lens is attached to a convex surface of the single lens; and one side of the single lens is aligned with an observed object. The high-magnification power eyepiece of the utility model has the advantages of simple structure and excellent amplification effect. The magnification power of the high-magnification power eyepiece can reach 65 times; the relative aperture of the high-magnification power eyepiece can reach more than 4 times; the size of an imaging end surface of the high-magnification power eyepiece can be about 0.34 mm; and the resolution of an output image of the high-magnification power eyepiece can be about 150 line pairs.
