摘要： A fixed-focus projection lens, in order from an image side to an image source side along an optical axis, includes a first lens with negative refractive power, a second lens with positive refractive power, a third lens with negative refractive power, a fourth lens with positive refractive power, a fifth lens with positive refractive power, and a sixth lens with positive refractive power. The second lens is a biconvex lens. While projecting, a light enters the fixed-focus projection lens from the image source side, and passes through the fixed-focus projection lens. Further more, at least one surface of the first lens is aspherical, a refractive index of the second lens is greater than 1.8, and a refractive index of the fifth lens is greater than 1.7. Such arrangement helps to lower a spherical aberration of spherical lens, shortening the optical system, and effectively lower the distortion.

摘要： A wide angle lens includes, in order from an object side to an image side along an optical axis, a negative first lens, a negative second lens, a positive third lens, a positive fourth lens, a negative fifth lens, and a positive sixth lens, wherein the sixth lens is adhered to the fifth lens to form a doublet lens. In addition, the wide angle lens further satisfies the condition of SD2/R2>0.6, where SD2 is half of an effective aperture of a surface of the first lens which faces the image side, and R2 is a radius of curvature of the surface of the first lens which faces the image side. Whereby, the FOV of the wide angle lens can be greater than 140 degrees, and the wide angle lens is compatible with a large-sized, e.g., 1/2.3″, photosensitive component.
