Publication number: 20140029119Abstract: A fixed focal length lens includes a first lens group and a second lens group. The first lens group is disposed between a magnified side and a minified side and has a negative refractive power. The second lens group is disposed between the first lens group and the minified side and has a positive refractive power. The fixed focal length lens satisfies F/H>0.52, where F is an effective focal length of the fixed focal length, and H is an image height.Type: ApplicationFiled: January 17, 2013Publication date: January 30, 2014Applicant: Young Optics Inc.Inventors: Yu-Hung Chou, Ying-Hsiu Lin, Yuan-Hung Su, Shiu-Sheng Li
