Abstract
A compact optical imaging lens can include a front lens group, a rear lens group, and a reflective element to redirect light passing through the system. The reflective element can be placed in front of the front lens group or between the front and rear lens group. In some cases, multiple reflective elements can be used. The use of reflective elements can reduce the depth of the imaging system, allowing for more compact designs.
