  • Optical lens
    Patent number: 9645365
    Abstract: An optical 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 optical lens is capable of forming an image at the magnified side. F/H>0.52, where F is an effective focal length, and H is an image height. A viewing angle is greater than 116.7 degrees.
    Type: Grant
    Filed: November 14, 2014
    Date of Patent: May 9, 2017

  • Fixed focal length lens
    Patent number: 8908292
    Abstract: 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.
