The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens are disposed in order from an object side to an image side. | 02-26-2009 |
| 20090052060 | IMAGING LENS WITH HIGH RESOLUTION AND SHORT OVERALL LENGTH - An exemplary imaging lens includes, in this order from the object side to the image side thereof, a first lens of positive refraction power, a second lens of negative refraction power, a third lens of positive refraction power, and a fourth lens of negative refraction power. The imaging lens satisfies the formulas of: (1) 0.5| 02-26-2009 | |
| 20090059384 | PROJECTION LENS WITH HIGH RESOLUTION AND REDUCED OVERALL LENGTH - An exemplary projection lens includes, in this order from the magnification side to the minification side thereof, a negative lens group having negative fraction of power, and a positive lens group having positive fraction of power. The positive and negative lens groups each include a number of positive and negative lenses. The focal length of the projection lens is adjustable. The projection lens satisfies the formulas of: â256, where F1, and F2 respectively represent the effective focal lengths of the negative lens group and the positive lens group, Fw is the shortest effective focal length of the projection lens, and Vg2 is the average of the Abbe number of the positive lenses in the positive lens group. | 03-05-2009 |
